As a new user of code_saturne, I wish to get the answer to these questions
1- How to display the mesh, I mean the meshes that are supplied with the tutorials
2- How to know the programme is running, is there a way to display the residuals even on the text window or any other indicator just to know it is running?

Hi Ahmed,

OK I'm not a developer but I can offer something up. Firstly, I don't know if this forum is the best to ask about code_saturne; maybe consider CAELinux forum or the forum of this group http://cfd.mace.manchester.ac.uk/twiki/bin/view/CfdTm

1. I don't it is possible to view the meshes supplied with the tutorials unless you have the original meshing package, usually Simail or I-DEAS. Maybe they can be converted by OF1.5 and viewed in paraview (I dont know about this)?


2. If you type in cs_info into the terminal you will see that grace can be used to view residuals. For this,look at the following tutorial if u havent done so

Good luck

BTW Thanks for the heads up on this great OS package

Hello all,

I'm part of Code_Saturne development team so I think I can answer your questions

1. To view the meshes you can run the mesh checker script

check_mesh -m "filename"

and then go in the check_mesh.ensight directory. The script creates a graphical output in EnSight Gold format that can be read by ParaView.
Two Ensight "cases" can be viewed, the first one called PREPROCESSOR.case with which you can check the boundary conditions definition, the second one called QUALITY.case with which you can check some quality criteria (non-orthogonality, warped faces, ...).

2. To check if the "something" is running, the first solution would be do to a "top" in a terminal and look for a process called cs13.exe (or cs14.exe depending on Code_Saturne version) for the "kernel" executable, or ecs for the preprocessor. The second idea would be to go the temporary run directory, something like

/home/user/tmp_Saturne/$STUDY.$CASE.$DATE

and then check the listing file. This the main listing output in which you can check at which time-step the code is, the residuals and so on.

Indeed we (Code_Saturne developpers) don't go everyday on this forum, so this maybe not the best solution to get some help from us . We are about to open our own forum (just a few fixes left...) in a couple of weeks hopefully! Meanwhile, you can contact us by e-mail saturne-support@edf.fr. The CFD group at the University of Manchester is another option are we are in touch with them.

Hope that helps!

Regards,
David
