Elmer Discussion Forum

hello again, thanks for the assistance so far. I studied some of the Contact3d... and Mortar3d... test cases available in Github as well as ElmerSolver manual. Based on them I made some simulation runs by modifying the sif file each time. But apparently the results do not seem to be correct. I belie...

Thanks a lot, I was able to select separate boundaries in ElmerGUI after meshing the geo file you sent.

So the correct method is to create physical surfaces on the geometry rather than the mesh.

Next I will try contact analysis from the reference of Github files.

I tried to create the geo file from the stp file I used for creating the mesh (.msh) file in Gmsh. I hope it is helpful.

Yes, I have also observed that ElmerGUI displays only boundary surfaces. But my concern is that, in the above case, all my physical surfaces that I created in Gmsh such as fixed boundary face, load boundary face and contact faces seems to be getting merged in Elmergui. This is making difficult to as...

Thanks for the advice. It was helpful. just curious to know if multi-body (3D) contact analysis is possible in Elmer using ElmerGUI. I was trying to import two 3D models in the same file from Gmsh to ElmerGUI. The file had both necessary volumes and surfaces (physical entities) such as contact faces...

Thanks Kevin

I have tried with normal force equivalent to pressure on the surface (pressure=normal force/surface area). With this option, results are not coming out to be correct. I am trying to find the gap.
Do you know the option of applying pressure directly on surfaces?

Hi all,
Does anyone know how to apply pressure on surfaces in linear elastic model of ElmerGUI?
There is only option for applying pressure on body properties (as body force).

Thanks a lot for the advice. I will work on it.

Hi Folks, I am new user of Elmer and struggling in initial phase of using this tool. It would be great if anyone from the community can help me in following issue currently i am facing. As we know that while importing any geometry into Elmer GUI, it starts meshing same with default meshing parameter...
