mymesh.converter.quad2quadratic

mymesh.converter.quad2quadratic(NodeCoords, NodeConn, cleanup=True)

Converts a 4 node quadrilateral mesh to 8 node quadrilateral mesh. A new node is placed at the midpoint of each edge.

Parameters:

• NodeCoords (array_like) – List of nodal coordinates.

• NodeConn (array_like) – Nodal connectivities for a 4-node quadrilateral mesh

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

Returns:

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

• NewConn (np.ndarray) – Nodal connectivities for the 8-Node quadrilateral mesh
