2D flow with Code Saturne was created by Matthew Bondy

I have been attempting to analyze a 2D mesh created in salome. However, I have been unable to get Saturne to recognize the boundaries (lines) set in Salome. Any thoughts? Am I just making some simple error?

Thanks,

C_S doesn't 'work' in 2D. However, you can extrude your mesh in the Z direction and add 'symmetry' on the two faces that are normal to Z.

Does that make sense? First case in the C_S tutorial has the answer.

I figured the issue was my attempted selection of lines for boundary conditions. Is there a similar limitation for OpenFOAM? I have found myself unable to convert 2D meshes from Salome but they work if they come from Gambit. Then again the Gambit meshes then appear somewhat 3D in paraview.

Thanks for the information. I was also unaware of any tutorials other than the step tutorial that comes with CAELinux. Is there any other site to go to for support on Code Saturne? The one website I found (the creators, I believe) was quite sparse.

~/code_saturne/Noyau/ncs-1.4.b/doc/TUTORIAL has the tutorial, and the folder above has some other docs. If they are not there/created, you can enter the folder with a terminal and type 'make'

No, I haven't really found any sites for C_S, however EDF is going to launch a forum aimed at C_S, but it's coming along very slowly unfortunately :unsure:

David Monfort frequents this forum and is very helpful, so post your problems here.

About paraFOAM; I don't know - I hate that program. ...at least till I figure it out :whistle:

How do I ensure unit consistency with CS? My Salome geometry is in mm.
I suppose I could just run a simulation and see how reasonable the results are.

I have a few gambit meshes I am trying to use. Is this possible? The documentation seems to indicate that this can be done. However, I think my dependence on the GUI is getting me into trouble. I should just go cold turkey and get rid of windows...

Thanks,

Hi Matthew,

Probably a bit late but here are some answers:

indeed the website is a bit "sparse" but we are about (at last!) to launch a forum and bug-tracker, say in a couple of weeks now (I do not dare to give a precise timeline now )
Code_Saturne is unaware of units: everything is in understood as meters (standard units) in the code, but if needed you can convert your mesh from mm to m in the usmodg.F subroutine
Gambit meshes (in neutral format) can be read straightforwardly (from within the GUI as well)

Be careful with the tutorial as they have not been updated recently, and therefore do not work with the latest version (we will only update them when the next version is about to be released, not at each beta snapshot).

Kind regards,
David
