Code_Saturne - Compressible module

I am trying to do an analysis using the compressible module of Code_Saturne. Below is the messages returned from executing the lance script:

Single processor Code_Saturne simulation

... and the listing file tells this error:

The kernel variables number 9 and the calculated one by the GUI 6 are not the same.

Apparently is is not something simple, and I have tried to find a hint in the manuals and the internet.

Can someone help, please.

Hello Torben,

I'm apparently a bit late... however, I can give you some elements of answer.

Currently, Code_Saturne compressible module cannnot be setup via the graphical interface. You should instead use the different user routines available in users/cfbl and avoid the interface.

uscfx1 and uscfx2 gives the basic setup for the different options of the compressible module, uscfcl for the boundary conditions, uscfpv for the variable physical properties, uscfxi for the variables initialization... More information can be found in the user guide.

ps: the comments in the user routines have been translated in English in the latest version (2.0-rc1) <br /><br />Post edited by: David Monfort, at: 2010/03/27 22:18

Thank you, Monfort, for the answers and comments. I have also started a thread at the CFD and Turbulence Mechanics forum at the University of Manchester, also adressing use of the compressible module:

Look &gt;here&lt;

So, up to now I have some find of success in getting the basic parameters set by editing the relevant and launching the analysis. The simulation seems to work but stops after one or a few time steps. Significantly less than the NTMABS that I have asked for.

The listing file is uploaded &gt;here&lt; and most certainly tells me why, but unfortunately I still have not the full understanding of how the parameters interact.

If anyone here have the time to take a look I will be grateful and - of course - share the results.
