Hello,
I created a volume mesh based on a simple cylinder in Netgen GUI 6.2.2004 with the option "Second order elements".
I exported the mesh in ELMER format but it seems there is an error in the mesh files. The information between mesh files are different:
mesh.boundary -> 306 type (quadratic triangle elements) ok
mesh.elements -> 510 type (quadratic tetrahedrons elements) ok
mesh.header -> indicates linear types: 303 and 504 (linear triangle and tetrahedron elements) (why?)
By using this mesh as this, the calculation in ELMER seems working. However there are pretty much triangles missing in the post-processing view of the .vtu files in Paraview.
I attached the geometry, the ELMER mesh and the .VTU output file of ELMER.
Thanks for helping.
Jeremie
