problem to get 2nd-order elements after nastran import
hello, I have the following question: when opening a nastran mesh containing quadratic Tetra10 elements:
gmsh Tetra10_Mesh.nas
all tetra elements in gmsh seem to be linear elements, and the number of nodes is reduced to the nodes at the corners.
(I can change the order of the elements in gmsh using "set order 2", but the curvature is then lost because there is no geometry behind, so this is not useful)
Strangly when importing the same mesh of Tetra10 in Ideas Format
gmsh Tetra10_Mesh.unv
all elements remain in gmsh of order 2
Can somebody explain please how I can import nastran Tetra10 elements maintaining the 2nd-order nodes?
many thanks!
