PCMGSetAdaptInterpolation#
Adapt the interpolator based upon a vector space which should be accurately captured by the next coarser mesh, and thus accurately interpolated.
Synopsis#
#include "petscksp.h"
PetscErrorCode PCMGSetAdaptInterpolation(PC pc, PetscBool adapt)
Logically Collective
Input Parameters#
pc - the multigrid context
adapt - flag for adaptation of the interpolator
Options Database Keys#
-pc_mg_adapt_interp - Turn on adaptation
-pc_mg_adapt_interp_n
- The number of modes to use, should be divisible by dimension-pc_mg_adapt_interp_coarse_space
- The type of coarse space: polynomial, harmonic, eigenvector, generalized_eigenvector
