Elmer Discussion Forum

Yes the splitting can be avoided by grouping all of the surface boundaries that you want to be boundaries in salome. You have 1 group the outer surface, so elmer defaults all of the remaining ones into the last boundary. To avoid splitting you must group all of your boundaries you need in salome ju...

I will see what I can do for posting a model. Also, unless I should put all things done through the GUI on the ElmerGUI forum regardless of the situation, I deemed that this is generally unrelated to the GUI itself as opposed to an issue with how the solver is launched. I can certainly provide a scr...

I am trying to simulate the transient cooling of a tube from a steady state condition where the only heat transfer mode carrying energy away is radiation. I have already obtained the steady state results that I need, and I have followed the instructions to perform a restart to the best of my knowled...

I'm trying to simulate a radiative heat transfer + linear elasticity model with a mesh I built in Salome. The log file simply says the parallel solver failed to start. I'm using the Windows GUI+MPI binary compiled shortly before December 23, 2023. I have previously used the parallel solver with succ...

Splitting is not necessary in ElmerGUI if you manage everything in Salome. I use partition instead of cuts, because with cuts you end up with multiple parts and have to worry about coincident nodes and mis-matching boundaries, etc. Using partitions you end up with 1 part, 1 mesh, with multiple bodi...

I take that back. It did not work as expected. The magnets did import properly before splitting surfaces because a region of high refinement in the air at the center of the circle ended up being joined as a single body. This is of course not what I want. When I went to split those bodies, the ends o...

This would be my work flow for this type of meshing The documents and Salome file are here https://github.com/mrkearden/modeling Thank you! Between your last two posts and a bit of experimenting I have made the meshing import into Elmer properly. However, the exact reasons why the solution was the ...

ElmerGUI displays bodies by displaying their boundary surface, if the boundary has 2 parents then 1 body will display and the other will not. It only uses the first parent. The better approach is to use groups in Salome. Groups of volume elements become bodies and groups of surface elements become ...

Thank you, Kevin. I will try to do that. It might take me a bit to muddle through understanding how to perform those operations, but I will certainly be trying them. I had absolutely zero knowledge that this was how decisions in Salome affected Elmer.

Here is the image of the mesh in Salome.
