mymesh.converter.surf2tris

mymesh.converter.surf2tris(NodeCoords, NodeConn, return_ids=False, return_inv=False)

Decompose all elements of a surface mesh to triangles.

Parameters:

• NodeCoords (list) – List of nodal coordinates.

• NodeConn (list) – Nodal connectivity list.

• return_ids (bool, optional) – Element IDs of the tris connected to the original elements, by default False

• return_inv (bool, optional) – If True, return element IDs of the original elements that correspond to the triangular elements, by default False

Returns:

• TriCoords (list) – Nodal coordinates of the generated triangles.

• TriConn (list) – Nodal connectivity list of generated triangles.

• ElemIds (list, optional) – If return_ids = True, a list of the element ids of the new triangles for each of the original elements.

• inv (np.ndarray, optional) – Array of indices that point from the triangular mesh back to the original mesh
