A newly introduced feature is the rewritten GUI code, which is based on PyQt4. Therefore, we have to install PyQt4 module rather than tk/tix for CS 1.3.3.
:/$ sudo apt-get install python-qt4
The compiling process of 1.4.0 is quite similar to 1.3.3. You can even use the same instruction I wrote to compile the code and then use it.
Another very useful tutorial on installation of Code_Saturne 1.4b on Ubuntu 8.04 can be found from the CAE Linux wiki, although it is a bit outdated.
It is also worth mentioning that if you already have a compiled version of CS 1.3.3, you can reuse all the existing libraries in "src". Just specify them in the "setup" configuration file and you do not need to compile them again.
Ps, I couldn't make the parallel computing in CS 1.4.0 work yet. I found if I use more than one CPUs, they will be endlessly running all the time. I am still looking for the probably existing errors. Please give hints if you already solved it. Many thanks in advance.
