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
