Hi Elmer team,
I'm doing a laminar flow NS simulation using a mesh created in Gmsh. The mesh is 100% prisms, if I use linear 6 noded elements the simulation runs perfectly but if I change the mesh order to second order 15noded elements (715) the simulation terminates early see attached log (same mesh in both cases just a different element order). Could it be the element node order is incorrect for the 2nd order elements? I use ElmerGrid to do the conversion i.e.
elmergrid 14 2 file.msh -autoclean -metis 8 3 ( the same for both linear and 2nd order elements)
Best regards
Mark
