mymesh.converter.quad82linear

mymesh.converter.quad82linear(NodeCoords, NodeConn)

Converts a 8-node quadrilateral mesh to a 4-node quadrilateral mesh. Assumes a 8-node quadrilateral numbering scheme where the first 4 nodes define the quadrilateral vertices, the remaining nodes are thus neglected.

Parameters:

• NodeCoords (array_like) – List of nodal coordinates.

• NodeConn (array_like) – Nodal connectivities for a 8-Node quadrilateral mesh

Returns:

• NodeCoords (array_like) – List of nodal coordinates (unchanged from input).

• NewConn (np.ndarray) – Nodal connectivities for the equivalent 4-Node quadrilateral mesh
