node order for 10-node tet #390

Closed cwsmith closed 1 year ago

Copied from the SCOREC slack: Q:

Good morning all. I am trying to get the numbering for a 10 node tetrahedral to follow the same convention as abaqus to print out an element connectivity matrix. Is there a command to do this in PUMI? I have the elements and the capability to print out all 10 nodes, just need the additional capability to print out the nodes in this order to export to an external FEM mesh. Thanks.

A:

AFAIK, there isn't an API that supports permuting the dof holders/nodes for a given entity. Figures 6 and 7 in the pumi users guide (https://scorec.rpi.edu/pumi/PUMI.pdf) give the vtx, face, and edge order for tets used in PUMI. I assume with this info and the PUMI field query function to get the 'nodes'/dof holder associated with the edges you could write the abaqus order.
