Hi!

I'm trying to use MeshTools::Modification::distort together with TET10.
However, after this operation the mesh seems to no longer be
tetrahedral, and I'm suspecting that this is the reason I'm getting a
lot of negative jacobian problems. Is there a way in libmesh to distort
a TET10 mesh while preserving the tetrahedral property? Here are links
to screenshots from gmsh of the libmesh generated mesh, with and without
having afterwards applied distortion:
