For some time, I have heard good opinions about Code Saturne, an open source, and free CFD solver (you can have a very first contact here

2007.rmll.info/IMG/pdf/RMLL07Sc_CodeSaturne_EDF.pdf

I tried to install it on my open suse partition, but the result was not positive, it seems that open suse has memory management problems with hdf5 & med libraries (needed to import and export geometry and post processing data with Salome ).
Recently I added a Debian partition to my computer and decided to have another go with the installation. Every thing went OK except med (Still have problems installing the right med, but nothing with memory management), any way, except med, the rest is running fine. This week end, I printed the first tutorial and rolled up my sleeves.

First, I would like to ask the readers that have negative opinions about Open source programmes to set aside their negative waves till they try this one by themselves.
The programme has a nice graphical user interface with a file tree so well structured that does not allow you to forget any step. It reminds me of The old Fluent text menues, that led you through the solution procedure a step by step so here they rightly deserve an A+ grade.
A very nice GUI indeed.
Upwind and central discretizations are available
A bunch of Turbulence models spanning from the old Prandtle mixing length model to the latest k-omega. Another A+ here.
The Energy equation (Both in temperature and enthalpy) are available, so another A+
A bunch of physical models from simple pipe cases to nuclear reactors and combustion models, here they deserve a mark of excellence above A+.
In short, I invite my fellow readers of this forum to try it and sure they will change their minds about open source codes, period period period.
Very few things annoys me about this programme, one such a thing is the way they treat gravity forces, my first impression was this programme is good for outer space applications but I am wrong, I just need to go through their theory manual.
Another negative point is how the different libraries needed to compile the programme are scattered along different sites, yes, they indicate links to these sites, but what about the correct version number of each library, my problem now is to find the correct med library that can be compiled on my Debian partition and my 64 bits Open Suse partition.
We can easily forget about these last two remarks, and Enjoy a well written programme with an excellent GUI.
By the way, the programme can export the results in Ensight format, so our good friend ParaView can read them.
Enjoy your CFD computations.

If after trying this Open Source programme you find I am wrong, Please put your opinion here.
I hope one of these days we convice Johnas and Peter to have a dedicated forum for such an excellent Free Open source programme.

Good Luck to all, and thank you for patiently reading this post.
