Hello Jérôme, Thank you for your detailed reply and all these informations. I'll take the time to read the reference you suggest and to test modifications you propose. Concerning the diverging simulation, here are the used settings (almost the same the last files you sent me, except for an initial s...

Hello Yvan, Thank you for these clarifications, I didn't think the gap of memory usage between the two approaches would be that wide. Regarding the convergence of my simulations, I noticed a strong impact of the following parameter : cs_navsto_param_set(nsp, CS_NSKEY_GD_SCALE_COEF, "5e3");...

Hello, I carried out some tests based on the previous cs_user_parameters file (with gravity, but no physics about solidification at this time), here are some reports : => With the 2D square 0.1m*0.1m case previously described, simulations seems to make sense (negligible velocity), but I noticed a ve...

Hello Jérôme,

Thank you very much for your help.

I'll try these modified settings in some configurations, and will give you feedback if you're interested.

Best regards,
Matthieu

Hello Jérôme, Thank you for your answer. It's ok concerning access to MUMPS library and solver. I tried to use it, but temperature is diverging in my test (cf. joined files). Regarding "classical" solvers available in CS, is there a better option than the used GCR solver for velocity? I'm ...

Hello Jérôme, Thank you for you answer. Here is my setup.log file. Concerning the MUMPS solver, it appears I can't use it ("cs_user_parameters: MUMPS is not available" if I try a simulation with the linked source file). I have an installed libmumps on my server, but I just checked and code...

Here are some additional files concerning obtained results (listing file and images of Vz component field).

Best regards,

Hello everyone, I would like to make a demonstration case of segregation phenomena during the solidification of a binary alloy. To do this, I'm trying to use the CS solidification module with CDO scheme approach (v8.0.2), and I'm facing a problem I don't understand concerning the gravity considerati...

Hi Matthieu, I am trying to install the version for OpenFOAM v2106. What versions of the med and hdf5 libraries did you use to make it work correctly? Hi Finzeo, I'm using the foamMeshToMED tool with following versions : - hdf5 1.10.5 - MED 4.1.0 From memory, it's still OK with hdf5 1.10.6 and MED ...

Hello, Concerning Salome, I read the 9.10 release notes with the following section : Polyhedral meshing SMESH is now capable of producing Polyhedral meshes, we produce these via mid-point Dual transformations of tetrahedral meshes. Polyhedral meshes which are gaining in popularity in various numeric...
