Incorrect node list for high-order (>5) prism and hex elements
The node lists for high-order (>5) prism and hex elements are missing certain face nodes while also containing duplicates of other nodes. If I add the surfaces of the elements as a physical group, the node lists for the surfaces are correct.
I am using gmsh 2.13.2 and I've attached a tarball including a simple script that will create a single 8th order hex element and save the mesh to hexa.8.msh. It also includes similarly created 6th-9th order hex and prism mesh files.
