Detailed Description

columns of layers that neighbor the local domain

Field Documentation

sc_array_t p6est_ghost_t::ghosts

An array of column-layers which make up the ghost layer around p6est.

Their piggy3 data member is filled with their owner's tree and local number (cumulative over trees). Quadrants are ordered in p4est_quadrant_compare_piggy order. These are quadrants inside the neighboring tree, i.e., p4est_quadrant_is_inside is true for the quadrant and the neighboring tree.array of p2est_quadrant_t type

p4est_locidx_t* p6est_ghost_t::mirror_proc_fronts

like mirror_proc_mirrors, but limited to the outermost octants.

This is NULL until p4est_ghost_expand is called

sc_array_t p6est_ghost_t::mirrors

An array of local quadrants that touch the parallel boundary from the inside, i.e., that are ghosts in the perspective of at least one other processor.

The storage convention is the same as for ghosts above.array of p4est_quadrant_t type
