Dear All,
Regarding my previous question I found that there is an option in
Gmsh to get higher order elements for reflecting curvature of the
edges into .xml file. However, when I increase the order of the
element from 1 to a higher order (e.g. 3) and convert the .xml file
to .vtu file I got the message:
Warning: Level 0 assertion violation
3D deformed Jacobian not positive (element ID = 359)
(first vertex ID = 206)
and the mesh that MeshConvert obtained from Gmsh's .msh file looks
like:
As far as I know "Jacobian not positive" means there are
intersecting elements. What may be the reason for this problem?
Regards,
Kamil

Dear
All,
I mesh a circular pipe in Gmsh very coarsely as below and turn it
into a xml file via MeshConvert. However, the curved edge
information is not transferred to the xml file (as seen in the
figure at right). How can I succeed this? Is there any way of
doing it in Gmsh or is this directly related with Nektar++ ?
