gustaf.utils.connec

gustaf/gustaf/utils/connec.py.

Useful functions for connectivity operation. Ranging from edges to volumes. Named connec because connectivity is too long. Would have been even cooler, if it was palindrome.

Functions

faces_to_edges(faces)	Compute edges based on following edge scheme.
hexa_to_quad(volumes)	Computes quad faces based on following index scheme.
make_hexa_volumes(resolutions)	Given number of nodes per each dimension, returns connectivity information of structured hexahedron elements.
make_quad_faces(resolutions)	Given number of nodes per each dimension, returns connectivity information of a structured mesh.
range_to_edges(range_[, closed, continuous])	Given range, for example (a, b), returns an edge sequence that sequentially connects indices.
sequence_to_edges(seq[, closed])	Given a sequence of int, "connect" to turn them into edges.
sequentialize_edges(edges[, start, ...])	Organize edge connectivities to describe polygon or a line.
sorted_unique(connectivity[, sorted_])	Given connectivity array, finds unique entries, based on its axis=1 sorted values.
subdivide_edges(edges)	Subdivide edges.
subdivide_quad(mesh[, return_dict])	Subdivide quads.
subdivide_tri(mesh[, return_dict])	Subdivide triangles.
tet_to_tri(volumes)	Computes tri faces based on following index scheme.
volumes_to_faces(volumes)	Guidance function for tet_to_tri and hexa_to_quad.
