mymesh.converter.linear2quadratic

mymesh.converter.linear2quadratic(NodeCoords, NodeConn, Type=None)

Convert linear (first-order) elements to quadratic (second-order) elements. See also Element Types.

Parameters:

• NodeCoords (array_like) – List of nodal coordinates.

• NodeConn (array_like) – Nodal connectivity list.

• Type (str) – Mesh Type (‘surf’ or ‘vol’). This helps resolve ambiguities between 4-node quadrilaterals and 4-node tetrahedra. If not provided, Type will be detected using mymesh.utils.identify_type()

Returns:

• NewCoords (list) – Nodal coordinates of the second order mesh

• NewConn (list) – Nodal connectivity list of the second order mesh
