mymesh.converter.tet2quadratic

mymesh.converter.tet2quadratic(NodeCoords, Tet4NodeConn, cleanup=True)

Converts a 4 node tetrahedral mesh to 10 node tetrahedral mesh. A new node is placed at the midpoint of each edge.

Parameters:

• NodeCoords (array_like) – List of nodal coordinates.

• Tet4NodeConn (array_like) – Nodal connectivities for a 4-node tetrahedral mesh

• cleanup (bool) – Cleanup/merge duplicate nodes created during the process, by default True

Returns:

• NodeCoords (np.ndarray) – New list of nodal coordinates.

• Tet10NodeConn (np.ndarray) – Nodal connectivities for the 10-Node tetrahedral mesh
