DMForestSetWeightCapacity#

During the pre-setup phase, set the capacity of the current process when repartitioning a pre-adaptation forest (see DMForestGetAdaptivityForest()).

Synopsis#

#include "petscdmforest.h" 
#include "petscdm.h" 
#include "petscdmlabel.h" 
PetscErrorCode DMForestSetWeightCapacity(DM dm, PetscReal capacity)

Logically Collective

Input Parameters#

  • dm - the forest

  • capacity - this process’s capacity

Note#

After partitioning, the ratio of the weight of each process’s cells to the process’s capacity will be roughly equal for all processes. A capacity of 0 indicates that the current process should not have any cells after repartitioning.
