Enclosed volumes in ElmerGrid
Enclosed volumes in ElmerGrid
Is it possible to make something like this in ElmerGrid where you have one volume inside another volume, with the outer volume mesh and inner volume mesh sharing surfaces? I did it with gmsh, but I would really like to do it in ElmerGrid so I have more control over meshing parameters.

Hi
Sure, look at for example

And modify the Extruded Structure to
or something... Generally I have no aspiration to teach ElmerGrid since that just may lead to endless unfruitful questions. Therefore I would recommend it only for rather simple meshes. Unfortunately there does not seem to be proper structured mesh generators freely available so ElmerGrid native format still serves a purpose.

Fantastic. I am not exactly sure what the 15 does, but I extruded an extra layer and had to remove "15" to get a box inside a box. Using 0 as newmat seemed to the be trick. Thanks!

Hi
Nice if it works. The "15" was a copy-paste error that I removed, if somebody is wondering.
