mymesh.rays.BoundaryBoundaryIntersection#

mymesh.rays.BoundaryBoundaryIntersection(NodeCoords1, BoundaryConn1, NodeCoords2, BoundaryConn2, eps=0, return_pts=False)[source]#

Identify intersections between two surface meshes.

Parameters:

  • NodeCoords1 (array_like) – Node coordinates of the first boundary mesh

  • BoundaryConn1 (list, array_like) – Node connectivity of the first boundary mesh

  • NodeCoords2 (array_like) – Node coordinates of the second bounday mesh

  • BoundaryConn2 (list, array_like) – Node connectivity of the second boundary mesh

  • eps (float, optional) – Small tolerance parameter, by default 0, by default 1e-14

  • return_pts (bool, optional) – If true, will return intersection points, by default False.

Returns:

  • Intersections1 (np.ndarray) – Element ids from the first mesh that intersect with the second

  • Intersections2 (np.ndarray) – Element ids from the second mesh that intersect with the first

  • IntersectionPoints (np.ndarray, optional) – Coordinates of intersections (returned if return_pts=True)
