PCMGSetAdaptCoarseSpaceType#

Set the type of adaptive coarse space.

Synopsis#

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#

  • -pc_mg_adapt_interp_n - The number of modes to use

  • -pc_mg_adapt_interp_coarse_space - The type of coarse space: none, polynomial, harmonic, eigenvector, generalized_eigenvector, gdsw

Note#

Requires a DM with specific functionality be attached to the PC.
