NEPCISSSetRefinement#

Sets the values of various refinement parameters in the CISS solver.

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPCISSSetRefinement(NEP nep,PetscInt inner,PetscInt blsize)

Logically Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • inner - number of iterative refinement iterations (inner loop)

  • blsize - number of iterative refinement iterations (blocksize loop)

Options Database Keys#

  • -nep_ciss_refine_inner <inner> - sets number of inner iterations

  • -nep_ciss_refine_blocksize <blsize> - sets number of blocksize iterations

Note#

PETSC_CURRENT can be used to preserve the current value of any of the arguments, and PETSC_DETERMINE to set them to a default of 0 (no refinement).
