Function Documentation

t8_locidx_t t8_cmesh_ltreeid_to_ghostid(const t8_cmesh_t cmesh, const t8_locidx_t ltreeid)

Given a local tree id that belongs to a ghost, return the index of the ghost.

Parameters:

• cmesh – [in] The cmesh to be considered.

• ltreeid – [in] The local id of a ghost, satisfying t8_cmesh_treeid_is_ghost, thus num_trees <= ltreeid < num_trees + num_ghosts

Returns:

The index of the ghost within all ghosts, thus an index 0 <= index < num_ghosts cmesh must be committed before calling this function.
