Ensure mesh has only Tet-10 elements

Please login with a confirmed email address before reporting spam

I have a new app for the Apple Vision Pro that shows FE mesh and FE results in an immersive environment, but only for tet-10 elements. I have figured out how to use LiveLink Matlab to export all tet-10 elements that are created using the "Free Tet" mesher. However, when I display the mesh with the Vision Pro app, it shows a large portion of the mesh, but not all. I believe that's because of the "boundary and edge elements" that are created with the "Free tet" mesher. These are, possibly, triangular and line elements? Can I force the "Free tet" mesher (or another mesher in Comsol) to only generate tet-10 elements?

You are correct in that there are always elements of lower dimensions generated on boundaries, edges (and points, actually). But since you are using a Matlab script to extract the mesh, it should be possible to filter out only the solid elements.
