MatSTRUMPACKSetGeometricNxyz#

Set STRUMPACK https://portal.nersc.gov/project/sparse/strumpack/master mesh x, y and z dimensions, for use with GEOMETRIC ordering.

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatSTRUMPACKSetGeometricNxyz(Mat F, PetscInt nx, PetscInt ny, PetscInt nz)

Logically Collective

Input Parameters#

  • F - the factored matrix obtained by calling MatGetFactor() from PETSc-STRUMPACK interface

  • nx - x dimension of the mesh

  • ny - y dimension of the mesh

  • nz - z dimension of the mesh

Note#

If the mesh is two (or one) dimensional one can use 1, PETSC_DECIDE or PETSC_DEFAULT for the missing z (and y) dimensions.
