</div><br />
Welcome to my blog on CFD, numerical modelling and parallel programming. Though relevant things are included, the CFD part of this blog focuses on the packages <i>SALOME</i>, <i>Code_Saturne</i> and <i>ParaView</i> etc. The complete content can be directed by the <b>Labels</b> list on the right side.<br />

<b>All the posts here are kept updated</b>. Following or subscribing a blog is a good idea if it really helps. <i>Up to March 2012, as reported by Google, there are <b>90</b> friends who are following or subscribing my posts using Google</i>.<br />
<br />
The most popular posts are summarised as follows<br />
<br />
1. <span style="font-weight: bold;">Installation of SALOME on Ubuntu</span><br />
<br />
The latest SALOME version is <a href="http://code-saturne.blogspot.com/2011/07/salome-version-631-is-released.html" target='_blank'>6.3.1</a>. However I haven't tried this version; I am still using the 5.1.x.<br />
<br />
For 5.1.x the latest version is <a href="http://code-saturne.blogspot.com/2011/09/release-of-salome-version-516-and.html" target='_blank'>5.1.6</a>. The complete instruction, "<a href="http://code-saturne.blogspot.com/2010/05/installation-of-salome-513-on-ubuntu.html" target='_blank'>Installation of SALOME 5.1.3 on Ubuntu 10.04 (64 bit)</a>", should help when install SALOME 5.1.x onto Ubuntu; at least according to feedbacks, this works up to 5.1.4 onto Ubuntu 10.04 (32/64 bit). The tips also suit Ubuntu 9.10, if all packages are updated in the system.<br />
<br />
For Ubuntu 9.10, an older post is "<a href="http://code-saturne.blogspot.com/2009/12/installation-of-salome-512-on-kubuntu.html" target='_blank'>Installation of SALOME 5.1.2 on (K)Ubuntu 9.10 64 bit</a>". The notes might be slightly outdated.<br />
<br />
If preferring Ubuntu 9.04, it is also easy to install SALOME by only following "<a href="http://code-saturne.blogspot.com/2009/07/installation-of-salome-414-on-ubuntu.html" target='_blank'>Installation of SALOME 5.1.1 on Ubuntu 9.04</a>". The post actually helps up to the latest version 5.1.3.<br />
<br />
For those who still use the old 4.* versions of SALOME, "<a href="http://code-saturne.blogspot.com/2009/07/polishing-gui-of-old-salome-versions.html" target='_blank'>Polishing GUI of older SALOME versions</a>" is recommended to read.<br />
<br />
2. <span style="font-weight: bold;">SALOME tutorials</span><br />
<br />
"<a href="http://code-saturne.blogspot.com/2010/02/cfd-example-laminar-flow-along-2d.html" target='_blank'>CFD tutorial: laminar flow along a 2D channel - Part I</a>" is a brief tutorial on using SALOME to do the geometry modelling and meshing.<br />
<br />
More examples are still on the way.<br />
<br />
3. <span style="font-weight: bold;">Installation of Code_Saturne on Ubuntu</span><br />
<br />
The latest <a href="http://code-saturne.blogspot.com/2011/11/codesaturne-210-has-been-released.html" target='_blank'>Code_Saturne 2.1.0</a> is much easier to compile and install than ever. An instruction on this version is on the way. By the way I also successfully ported this version onto Windows 7.<br />
<br />
Since version 2.0 Code_Saturne started to adopt the typical source build and install procedure on Linux. By following "<a href="http://code-saturne.blogspot.com/2010/06/installation-of-codesaturne-20-rc1-on.html" target='_blank'>Installation of Code_Saturne 2.0-rc1 on Ubuntu 10.04 (64 bit)</a>" I am confident it would be an easy job for you. In the meantime, if you are also a SALOME user, I strongly recommend you to read "<a href="http://code-saturne.blogspot.com/2010/01/compile-codesaturne-with-salome-binary.html" target='_blank'>Compile Code_Saturne with SALOME binary libraries</a>" in order to reuse the binary libraries already shipped with SALOME.<br />
<br />
Two slightly outdated but helpful posts are "<a href="http://code-saturne.blogspot.com/2009/08/installation-of-codesaturne-200-on.html" target='_blank'>Installation of Code_Saturne 2.0.0 on Ubuntu 9.04</a>" and "<a href="http://code-saturne.blogspot.com/2010/03/installation-of-codesaturne-20-rc1-on.html" target='_blank'>Installation of Code_Saturne 2.0-rc1 on Ubuntu 9.10</a>".<br />
<br />
You can also try to test installing Code_Saturne with <b>apt-get</b>. Please read "<a href="http://code-saturne.blogspot.com/2010/05/apt-get-ideal-way-to-install-software.html" target='_blank'>apt-get, the ideal way to install the software onto Ubuntu</a>".<br />
<br />
The instruction on installation of the last stable version, 1.3.3, was written in "<a href="http://code-saturne.blogspot.com/2009/07/installation-of-codesaturne-140-on.html" target='_blank'>Installation of Code_Saturne 1.3.3 on Ubuntu 9.04</a>". On the other hand, for the version 1.4.0 the installation procedure is quite similar to that of 1.3.3, except 1.4.0 turned to use PyQt4 and Qt4. Please check "<a href="http://code-saturne.blogspot.com/2009/07/installation-of-codesaturne-140-on_24.html" target='_blank'>Installation of Code_Saturne 1.4.0 on Ubuntu 9.04</a>" to see how to use (Py)Qt4 instead of the python-tk and tix.<br />
<br />
4. <span style="font-weight: bold;">Code_Saturne tutorials</span><br />
<br />
"<a href="http://code-saturne.blogspot.com/2010/02/cfd-example-laminar-flow-along-2d_06.html" target='_blank'>CFD tutorial: laminar flow along a 2D channel - Part II</a>" gives a brief tutorial on how to apply Code_Saturne to solve a CFD problem.<br />
<br />
More examples are still on the way.<br />
<br />
5. <span style="font-weight: bold;">Installation and usage of ParaView</span><br />
<br />
Installation of ParaView is relatively easier and please read "<a href="http://code-saturne.blogspot.com/2009/07/installation-of-paraview-361-on-ubuntu.html" target='_blank'>Installation of ParaView 3.6.1 on Ubuntu 9.04</a>". The usage of ParaView is briefly illustrated by an example in the article "<a href="http://code-saturne.blogspot.com/2010/03/mei-is-easy-to-use-and-works-like-charm.html" target='_blank'>Post-processing with ParaView</a>".<br />
<br />
For the latest version of ParaView, please refer to <a href="http://www.paraview.org/paraview/resources/software.html" target='_blank'>its official site</a>.<br />
<br />
6. <span style="font-weight: bold;">GPGPU acceleration with CUDA techniques</span><br />
<br />
A basic idea of using NVIDIA CUDA and the template library <b>thrust</b> is shown in "<a href="http://code-saturne.blogspot.com/2010/05/simple-test-on-efficiency-of-thrust.html" target='_blank'>A simple test on the efficiency of thrust</a>". An example to use CUDA practically is "<a href="http://code-saturne.blogspot.com/2010/08/apply-cuda-to-solve-1d-heat-transfer.html">Apply CUDA to solve a 1D heat transfer problem</a>".<br />

The details of the new features are described on the <a href="http://research.edf.com/news-111020-86939.html" target='_blank'>corresponding news page</a>.<br />
<br />
The selective major features include:<br />
<ul type="disc"><li><strong>Packaging</strong>: <em>Code_Saturne</em> is now provided as a single package, grouping all existing libraries (BFT, FVM, MEI, libsyrcs). It also includes preliminary source code for SALOME plugin (CFDSTUDY module and <em>Code_Aster</em> coupling).</li>
<li><strong>Code coupling</strong>: <em>Code_Saturne</em> 2.1 can be coupled with SYRTHES 4.0.0-10 (at least). SYRTHES 4.0 is a complete rewrite of SYRTHES 3.4 with many new features and should shortly be released. <em>Code_Saturne</em> 2.1 also contains preliminary code for <em>Code_Aster</em> coupling (more to come on this topic in next versions).</li>
<li><strong>User interface</strong>: both the script user interface and the graphical user interface have been simplified and completed to enhance user experience. Just give a try to the new runcase script (and its Python overloading) and to the new features of the graphical interface (more to come also on this topic in next versions).</li>
<li><strong>New mesh readers</strong>: <em>Code_Saturne</em> pre- and post- processing has been updated to support CGNS 3.1 and MED 3.0 format. MED 3.0 is compatible with SALOME 6.3.</li>
<li><strong>Documentation</strong>: the user manual has been slightly improve and a Doxygen documentation of the sources is now available. An installation manual is now provided too.</li>
<li><strong>Configuration</strong>: a configuration file can be completed, either globally or by user, to setup some runtime options like the scratch directory, an optional mesh database or SYRTHES 4.0 version to be used.</li>
<li><strong>Automatic V&V</strong>: a tool for automatic run of <em>Code_Saturne</em> has been developped, enabling the user to automatically run simulations, plot graphs and receive a PDF report by e-mail. It can be very useful for automatic Verification & Validation, though it is still in the very early stage of development.</li>

I am graduating in September 2011 with a PhD degree from School of Electrical and Electronic Engineering, University of Manchester. I am looking for a numerical modelling job.<br />
<br />
I spent the past more than three years on the CFD simulations which are coupling between electric, thermal and fluid dynamic fields, from which I have accumulated rich experiences on modelling packages such as SALOME, Code_Saturne, Elmer, ParaView and COMSOL etc. I share experiences in this blog, which has also gained worldwide popularity.<br />
<br />
I have been programming in C/C++, C#, VB.NET and Matlab since 2002. I also have experiences in Python (the script widely used for automation of modelling and the software such as SALOME and ParaView etc) and Fortran (the user routine definition for Code_Saturne) etc. Meanwhile, probably as a bonus, I am a fan of open-source software, Linux and Mac OS X. I even wrote device drivers for Linux and ported the <a href="http://www.mysql.com" target='_blank'>MySQL</a> client tool running on desktops onto embedded Linux platforms.<br />
<br />
I bear high interests in numerical modelling and would like to pursue a career in this field. If you have relevant opportunities, please drop me an email (salad00 at gmail dot com). I really appreciate your help very much.saladhttp://www.blogger.com/profile/17358271153894097966noreply@blogger.com12tag:blogger.com,1999:blog-8291601264811780727.post-84040634118809526462011-08-21T20:25:00.001+01:002011-08-21T20:37:25.133+01:00CUDA HeatTransfer1D program on Mac OS XI recently ported <a href="http://code-saturne.blogspot.com/2010/08/apply-cuda-to-solve-1d-heat-transfer.html">the CUDA program for 1D heat transfer</a> onto Mac OS X 10.6.8 and CUDA 4.0.31.

<a href="http://downloads.vmware.com/d/info/desktop_downloads/vmware_fusion_for_the_mac/3_0" target='_blank'>VMware Fusion 3.1.3 (416484)</a> has been release at the end of May. Bugs were fixed and more importantly, Ubuntu 11.04 has been officially supported. The previous version needed <a href="http://blog.breadncup.com/2011/02/26/vmware-tool-patch-for-linux-kernel-2-6-3738/" target='_blank'>patches</a> for its VMware tool because of its incompatibility to Linux Kernel 2.6.37/38.<br />
<br />
<span style="font-weight: bold;">4. Firefox 5</span><br />
<br />
Mozilla greatly shortened its new version release periods. As a convention Microsoft IE team sent Mozilla a cupcake for launching Firefox 5.<br />

[<a href="http://www.salome-platform.org/forum/forum_14/874023090#702034491" target='_blank'>1</a>]<br />
<br />
Part of the improvements and features this new version will bring to us can be referred from [<a href="http://www.salome-platform.org/forum/forum_10/770035702#907754799" target='_blank'>2</a>], listed as<br />
<ul type="disc"><li>Automatic meshing of boundary layers</li>
<li>SMESH: Histogram of the quality controls</li>
<li>Option Single/Multi file dump</li>
<li>"RemoveFromStudy" Function</li>
<li>Hide/Show Icon (as in paraview)</li>
<li>GEOM: Performance enhanced when manipulating large models</li>
<li>SMESH: Mesh common borders</li>
<li>SMESH: detection of over-constrained elements</li>
<li>SMESH: create a new mesh from a selected group or from selected elements</li>
<li>SMESH: Create a clipping plane on several groups</li>
</ul>Additionally the MED library version will be 3.0. This is a major change since the API is not compatible with the previous version. This version will read MED files of both format 2.2 and 3.0 and will write format 3.0.<br />
<br />
In version 6.3.0 it will be possible to define viscous layer (<a href="http://www.salome-platform.org/forum/forum_10/46780604/552308981/Inflation_Layer.GIF" target='_blank'>inflation layers</a> in ANSYS) [<a href="http://www.salome-platform.org/forum/forum_10/46780604#157188498" target='_blank'>3</a>]. It will be defined as an additional hypothesis for the 3D algorithms Netgen, GHS3D and Hexahedron, and the parameters will include:<br />
<ul type="disc"><li>Total thickness</li>
<li>Number of layers</li>
<li>Stretch factor</li>
</ul>The example of viscous layers defined on tetra and hexa meshes, David posted on the SALOME forum, is<br />

<br />
<a href="http://paraview.org/paraview/resources/software.html" target='_blank'>http://paraview.org/paraview/resources/software.html</a><br />
<br />
I repost the Release Notes from the email list as follows:<br />
<br />
<span style="font-weight: bold;">ParaView 3.10</span><br />
<br />
This release features notable developments, including mechanisms to incorporate advanced rendering techniques, improved support for readers and several usability enhancements and bug fixes.<br />
<br />
For the 3.10 release, we have added 60 new readers. The new readers include: ANSYS, CGNS, Chombo, Dyna3D, Enzo, Mili, Miranda, Nastran, Pixie, Samrai, Silo, and Tecplot Binary. A full listing of supported readers can be found in the ParaView Users Guide. We also added the ability for developers to create ParaView reader plugins from previously developed VisIt reader plugins. You can find a full guide on how to do this on the VisIt Database Bridge: <a href="http://www.paraview.org/Wiki/VisIt_Database_Bridge" target='_blank'>http://www.paraview.org/Wiki/VisIt_Database_Bridge</a>.<br />
<br />
With this release we have rewritten the ParaView User's Guide and are making it freely available for the first time. The complete guide can be obtained in the help system or online at:<br />
<a href="http://paraview.org/Wiki/ParaView/Users_Guide/Table_Of_Contents" target='_blank'>http://paraview.org/Wiki/ParaView/Users_Guide/Table_Of_Contents</a>.<br />
<br />
We have included a Python-based calculator which makes it possible to write operations using Python. The Python calculator uses NumPy, which lets you use advanced functions such as gradients, curls, and divergence easily in expressions. Also the NumPy module is packaged in the ParaView binary and is importable from the ParaView Python shell.<br />
<br />
There should also be a marked performance improvement for users dealing with large multi-block datasets. We have cleaned up the rendering pipeline to better handle composite datasets, avoiding the appending of all blocks into a single dataset as was done previously.<br />
<br />
To better utilize multiple cores on modern multi-core machines, by default ParaView can now run using a parallel server, even for the built-in mode. This enables the use of all the cores for parallel data processing, without requiring the user to start a parallel server. ParaView binaries will also be distributed using an MPI implementation, making this feature available to users by simply downloading the binaries. Since this is an experimental feature, it is off by default, but users can turn it on by checking the Auto-MPI checkbox in the application settings dialog.<br />
<br />
Additionally, the 3.10 release includes several usability enhancements. 3D View now supports smart context menus, accessed by right-clicking on any object in the 3D View to change its color, representation, color map and visibility. Left-clicking on an object in the 3D View makes it active in the pipeline browser. Within the spreadsheet view, sorting is now supported and an advanced parallel sorting algorithm ensures that none of the benefits of the spreadsheet view, such as streaming and selection, are sacrificed. Python tracing and macro controls are no longer hidden on the Python shell dialog and instead are now easily found on the Tools menu.<br />
<br />
For developers interested in adding support for advanced multi-pass rendering algorithms to ParaView, this release includes a major refactoring of ParaView's rendering pipeline. View and representations have been redesigned and users should see improved performance in client-server mode from reduced interprocess communication during rendering.<br />
<br />
LANL's MantaView interactive ray tracing plugin has been restructured to make it easier to use. Version 2.0 of the plugin is now multi-view capable and no longer requires ParaView to be run in a client/server configuration. Similarly both of LANL's streaming aware ParaView derived applications have been merged into ParaView proper in the form of a new View plugin. The underlying streaming algorithms have been rewritten to be more usable and extensible. Both plugins are available in standard binary package for the first time in this release.<br />
<br />

I am curious that all the source code were packaged into zip format. When trying to compile the source code, unfortunately, an error could occur as<br />
<br />
<code>:/$ ./configure<br />
Error: permission denied<br />
# the solution<br />
:/$ chmod +x configure<br />
</code><br />
The easy solution is modifying the attributes of the configure file.<br />
<br />
By this I succeeded to compile bft package; however when compiling fvm, I have got another error shown as<br />
<br />
<code>checking for bft version >= "1.0.0"... configure: error: in `/home/wu/saturne_packages/version 2.0.1/fvm-0.15.2':<br />
configure: error: compatible bft version not found<br />
</code><br />
I checked and found that the "make install" script of bft didn't install proper header files into the destination directory (by default, /usr/local/include). I guess this is a bug to fix, though the headers can also be copied manually.<br />
<br />
I didn't try the rest of the compilation yet.saladhttp://www.blogger.com/profile/17358271153894097966noreply@blogger.com10tag:blogger.com,1999:blog-8291601264811780727.post-30775968287977110462010-12-08T15:43:00.001+00:002010-12-08T15:45:22.974+00:00SALOME version 5.1.5 is releasedPlease read <a href="http://www.salome-platform.org/news/08-dec-2010-salome-version-5.1.5" target='_blank'>the piece of news</a>.<br />

I expect the tutorial "<a href="http://code-saturne.blogspot.com/2010/05/installation-of-salome-513-on-ubuntu.html" target='_blank'>Installation of SALOME 5.1.3 on Ubuntu 10.04 (64 bit)</a>" would still be helpful when install the latest SALOME 5.1.5 onto Ubuntu 10.10. I also look forward to receiving your testing feedback on this.saladhttp://www.blogger.com/profile/17358271153894097966noreply@blogger.com2tag:blogger.com,1999:blog-8291601264811780727.post-35188004855922678362010-09-21T22:09:00.002+01:002010-09-21T22:12:38.307+01:00MATLAB 2010b supports NVIDIA CUDA-capable GPUsFrom MATLAB 2010b, GPU support is available in <a href="http://www.mathworks.com/products/parallel-computing/" target="_blank">Parallel Computing Toolbox</a>. Using MATLAB for GPU computing lets you take advantage of GPUs without low-level C or Fortran programming.<br />
<br />
MATLAB CUDA support provides the base for GPU-accelerated MATLAB operations and lets integrate existing CUDA kernels into MATLAB applications. However, as a restriction, MATLAB only supports GPUs with CUDA compute capability version 1.3 or higher, such as Tesla 10-series and 20-series GPUs. This limitation is not from a light decision; it is actually due to the double precision support and the IEEE-compliant maths implementation of the CUDA capability version 1.3. Please see <a href="http://www.mathworks.com/matlabcentral/newsreader/view_thread/291689" target='_blank'>this thread</a> for more discussion.<br />
<br />
MATLAB GPU computing capabilities include:<br />
<ul><li>Data manipulation on NVIDIA GPUs</li>
<li>GPU-accelerated MATLAB operations</li>
<li>Integration of CUDA kernels into MATLAB applications without low-level C or Fortran programming</li>
<li>Use of multiple GPUs on the desktop (via the toolbox) and a computer cluster (via MATLAB Distributed Computing Server)</li>

The version introduces compatibility with Visual Studio 2010. You can debug, analyse, and profile your applications in Visual Studio 2010 instead of 2008.<br />
<br />
Unfortunately, you will still need the Microsoft v9.0 compilers installed in order to compile your CUDA C/C++ code when using Visual Studio 2010. These compilers ship with Visual Studio 2008, and older versions of the Microsoft Windows SDK.<br />
<br />
New Features in Parallel Nsight 1.5 RC:<br />
<br />
All: <br />
* Support for Microsoft Visual Studio 2010 in all Parallel Nsight components<br />
* Requires the 260.61 driver (available from the support site)<br />
* Bug fixes and stability improvements<br />
<br />
CUDA C/C++ Debugger:<br />
* Support for the CUDA 3.2 RC toolkit<br />
* Support for debugging GPUs using the Tesla Compute Cluster (TCC) driver<br />
* Support for >4GB GPUs, such as the Quadro 6000<br />
* CUDA Memory Checker supports Fermi-based GPUs.<br />
<br />
Direct3D Shader Debugger:<br />
* Debugging shaders compiled with the DEBUG flag is now supported.<br />
<br />
Direct3D Graphics Inspector:<br />
* Support for GeForce GTX 460 GPUs<br />
* Graphics debug sessions start much faster.<br />
* New Direct3D 11 DXGI texture formats are now supported for visualization.<br />
* Textures used in the current draw call's pixel shader are now viewable directly on the HUD.<br />
<br />
Analyzer:<br />
* Support for GeForce GTX 460 GPUs<br />
* NVIDIA Tools Extension (NVTX) events have been improved with color and payload.<br />
* NVIDIA Tools Extension (NVTX) API calls for naming threads, CUDA contexts and other resources<br />
* GPU-side draw call workloads from OpenGL and Direct3D are now traced.<br />

The version optimises correctly using gcc-4.5.0 and has been verified to run on OpenSuSE-11.3.<br />
<br />
Another good aspect is the debian packages prepared for this version, created for Ubuntu 10.04 LTS. Briefly, to install OpenFOAM in Ubuntu, execute the commands<br />
<br />
<code># add the openfoam source into the source list<br />
:/$ sudo echo "deb http://www.openfoam.com/download/ubuntu lucid main" >> /etc/apt/sources.list<br />
# refresh the package list<br />
:/$ sudo apt-get update<br />
# Install OpenFOAM<br />
:/$ sudo apt-get install openfoam171<br />
# Install Paraview<br />
:/$ sudo apt-get install paraviewopenfoam380<br />
</code><br />
Please refer to <a href="http://www.openfoam.com/download/ubuntu.php" target='_blank'>this page</a> for more information on the installation onto Ubuntu.saladhttp://www.blogger.com/profile/17358271153894097966noreply@blogger.com4
