DMPlexGetLocalOffsets#
Allocate and populate array of local offsets.
Synopsis#
Input Parameters#
dm - The DMPlex object domain_label - label for DMPlex domain, or NULL for whole domain label_value - Stratum value height - Height of target cells in DMPlex topology dm_field - Index of DMPlex field
Output Parameters#
num_cells - Number of local cells cell_size - Size of each cell, given by cell_size * num_comp = num_dof num_comp - Number of components per dof l_size - Size of local vector offsets - Allocated offsets array for cells
Notes: Allocate and populate array of shape [num_cells, cell_size] defining offsets for each value (cell, node) for local vector of the DMPlex field. All offsets are in the range [0, l_size - 1]. Caller is responsible for freeing the offsets array using PetscFree().
