Hello,

For low-level access, did you check the cs_user_solver.c examples ? All the cs_restart_* elements are for checkpoint/restart, and work in parallel.

Hello, There is no reason getfbr should not work when coupling with Syrthes. But using findpt in a loop on elements or faces is a bad idea, as it will cause a failure most of the time when running in parallel (it is a collective call, and must be called the same number of times by each rank). There ...

Hello, This is strange, as there does not seem to be any logging or backtrace of the cause of the crash. If your meshes are not too large and not confidential, you can post them here (along with the setup) so that I can check if I reproduce the issue. Otherwise, I could try to walk you through using...

Hello,

Do you have a backtrace for this crash ?

As before, even if the cause of the crash is different, both "listing" and "syrthes.log" might contain useful info, so please post them here.

Hello, Possibly, the meshes match, but the the selection criteria do not select all faces ? How many faces of each code are on each interface ? If most faces, but not all, are found, increasing the search tolerance (for curved areas) might help (but you need user subroutines to set this). Both codes...

Hello, Did you check the (fluid) "listing" and (solid) "syrthes.log" files as indicated in the script's error message ? The problem is probably a mesh location/interface problem, not an MPI problem. You do not need to change the files I posted last time, as they should work both ...

Hello, Does the foamToEnsightParts tool have any options ? When reading an EnSight file, the Code_Saturne preprocessor will generate boundary information if the EnSight file contains the " node id given " option (in the .case file), so if the converter can generate such a file, you should ...

Hello, Not all tutorials are in the source code repository, as several of them were added by various users of the code, but are not maintained by the dev team. Also, the tutorials are now updated less frequently than code releases, as 2 releases per year is difficult to follow, and a slightly out-of...

Hello, The tutorial examples are in the source code, but not in the installation. It would be a good idea to move them, but in the meantime, you can download them separately from the Subversion mirror: http://code-saturne.org/viewvc/saturne/branches/Version4_0/examples/ (for other versions than 4.0,...

Hello,

I'm not sure the problem is due to parrsm:

When you initialize hauteurfx:

hauteurfx = hauteurfx*0.d0 ! initialisation for security

you multiply something that might contain NaN's by zero.

Simply using:

hauteurfx = 0.d0 ! initialisation for security

would seem safer.
