Re: CS_4.0.2 and syrthes4.3.0 coupling MPI ABORT

Hello, The "addr2line" provided useful info, that is the crash seems to be in a write in "ecrire_geom_cplcfd" in Syrthes, which is a function used to write info about the geometry regarding coupled faces. I'll try to check if this is optional and can be deactivated, and keep you ...

Re: Error in computation of finer mesh

Hello,

Did you reduce the time step with the fine mesh ? The CFL numbers seem to be very high almost immediately, and are probably the cause of the crash.

Regards,

Yvan

Re: Centrifugal fan

Hello, I can't access Dropbox from the office. Did you check the the "inlet" and "outlet" meshes with a writer in the GUI ? Is the "auto" box checked ? Also check cs_user_parameters.f90 to see how to activate postprocessing of a cell-defined variable on the boundary. Wi...

Re: Code Saturne cluster installation

Hello, There is no specific distribution for Code_Saturne on clusters, but the installation procedure tries to be "cluster-friendly." On a cluster, installation is very similar to than n a workstation, with the addition of a "post-install" step, detailed in the installation manua...

Re: CS_4.0.2 and syrthes4.3.0 coupling MPI ABORT

Hello, Non, there is no way to use the coupling without MPI in current versions of the code(s). The crash occurs inside Syrthes, but is not easy to pinpoint. I am not even sure it occurs inside MPI, and I doubt MPI is the issue, as mesh location seems to work correctly ( Code_Saturne complains insid...

Re: One-way coupling and Two-way coupling of Lagrangian Part

Hello, Yes, the check does not seem too consistent, but in any case, the two way coupling has not been used much recently (or rather, semi-recently, by which I mean since the parallelization of the trajectory algorithm), so I would be very careful using it (i.e. compare with validation data or well-...

Re: free surface initial displacement initialization

Hello, I'm actually not knowledgeable enough in the ALE part of the code to tell you what needs to be computed first, an what works, what doesn't... xyzno0 is the "initial position" of vertices. Between depale (displacement) and impale (prescribed positions), I am not sure what is effectiv...

Re: CS_4.0.2 and syrthes4.3.0 coupling MPI ABORT

Hello,

Could you post the syrthes.log and Code_Saturne listing files again with this setup, to see if there is any difference ?

Regards,

Yvan

Re: free surface initial displacement initialization

Hello, No, these arrays are not currently defined as fields (they may be in the future), they are direclty defined as arrays in the albase module, so adding "use alebase" is enough. In any case, when referring to a variable you find in older tutorials or examples, search for that name in t...

Re: free surface initial displacement initialization

Hello, Checking your cs_user_initialization, I see that you should not be redifining: integer impale(nnod) double precision depale(3,nnod), xyzno0(3,nnod) (which are then uninitialized in your case) but: use albase If you still have issues after this fix, comment lines in your file (for example insi...
