Function Documentation

t8_locidx_t t8_cmesh_trees_get_ghost_local_id(t8_cmesh_trees_t trees, t8_gloidx_t global_id)

Given the global tree id of a ghost tree in a trees structure, return its local ghost id.

Parameters:

  • trees – [in] The trees structure.

  • global_id – [in] A global tree id.

Returns:

The local id of the tree global_id if it is a ghost in trees. A negative number if it isn’t. The local id is a number l with num_local_trees <= l < num_local_trees + num_ghosts
