Set the type of adaptive coarse space.
Synopsis#
#include "petscksp.h"
PetscErrorCode PCMGSetAdaptCoarseSpaceType(PC pc, PCMGCoarseSpaceType ctype)
Adapts or creates the interpolator based upon a vector space which should be accurately captured by the next coarser mesh, and thus accurately interpolated.
Logically Collective
Input Parameters#
pc - the multigrid context
ctype - the type of coarse space
Options Database Keys#
