Function Documentation

void t8_cmesh_set_join_by_stash(t8_cmesh_t cmesh, int **connectivity, const int do_both_directions)

Sets the face connectivity information of an un-committed cmesh based on the cmesh stash.

Note

This routine does not detect periodic boundaries.

Warning

This routine might be too expensive for very large meshes. In this case, consider to use a fully featured mesh generator.

Parameters:

• cmesh – [inout] An uncommitted cmesh. The trees eclasses and vertices do need to be set.

• connectivity – [inout] If connectivity is not NULL the variable is filled with a pointer to an allocated face connectivity array. The ownership of this array goes to the caller. This argument is mainly used for debugging and testing purposes. The dimension of connectivity are [ntrees,T8_ECLASS_MAX_FACES,3]. For each element and each face the following is stored: neighbor_tree_id, neighbor_dual_face_id, orientation

• do_both_directions – [in] Compute the connectivity from both neighboring sides. Takes much longer to compute.
