Multigrid Preconditioning

Good morning, how is the multigrid preconditioning working? I am getting an error about missing grd-files, so I assume that Elmer does not create the coarser meshes itself. Is this a valid assumption? So, I have to create the meshes myself? How should I organize them in my file system (in folders)? ...

Re: Salome: Elmer-plugin available

There is a minor update available. Multigrid solver settings will now be written to the sif-file.

Re: Turbulent Flow Simulations with Elmer - A Request

Hello, may I ask if there is any progress on this topic? Right now, I have exactly this use case: a complex mesh that relies on prims (due to extrusion) and turbulent flow. Right now I am getting the "706 bubbles not implemented" error (even if I switch off stabilization in the k-solver). I could re...

Choosing the best iterative method / Achieve convergence

I usually use iterative methods to solve my FEM-problems. Not only because I lack the math libraries for direct solvers, but also because you can run iterative methods easily on multiple cores. However, finding the right solver settings is often more trial and error than actual knowing. Especially, ...

Re: Salome: Elmer-plugin available

Thanks for the reply. There is an error during import and I have already checked the source and fixed it (hopefully).

Please download a new copy of the module and paste it in the directory. I have tested the new version on my machine and the module appears correctly.

Regards,
Rainer

Re: Salome: Elmer-plugin available

If you use the default directory then you do not have to add the system variable. So you may delete the entry. It could be possible that Salome gets confused by that. Additionally, you can check the terminal windows that appears when starting Salome for error messages. Sometimes the module is not lo...

Re: Elmer module for Salomé

Thanks for the hugs :) @Peter Unfortunately, I cannot help you with the MED-files. Additionally, I cannot see any benefits. In Salome you would have to export the mesh anyway as there is no direct access to Salomes mesh data. We currently have the mesh export directly linked to ElmerGrid. So there i...

Re: salomeToElmer - export Salome mesh to Elmer

Does your script maintain the naming of the mesh and mesh groups? If so, I could incorporate your script into my Salome plugin the emulates the Elmer GUI.

Thanks,
Rainer
