DMPlexMatSetClosureRefined

Insert values into A for the closure of a coarse-cell point, using indices from the associated refined subcells

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexMatSetClosureRefined(DM dmf, PetscSection fsection, PetscSection globalFSection, DM dmc, PetscSection csection, PetscSection globalCSection, Mat A, PetscInt point, const PetscScalar values[], InsertMode mode)

Not Collective

Input Parameters

• dmf - The fine DMPLEX

• fsection - The fine local PetscSection, or NULL to use DMGetLocalSection(dmf, ...)

• globalFSection - The fine global PetscSection, or NULL to use DMGetGlobalSection(dmf, ...)

• dmc - The coarse DMPLEX

• csection - The coarse local PetscSection, or NULL to use DMGetLocalSection(dmc, ...)

• globalCSection - The coarse global PetscSection, or NULL to use DMGetGlobalSection(dmc, ...)

• A - The matrix

• point - The coarse-mesh point whose refined closure is inserted

• values - The values to insert (row block of size equal to the fine-closure dof count, column block of size equal to the coarse-closure dof count)

• mode - The InsertMode (ADD_VALUES or INSERT_VALUES)

Note

This helper mirrors DMPlexMatSetClosure() but produces row indices from the fine subcells associated with the coarse point under regular refinement. It is used when assembling operators that couple a coarse cell to its uniform refinement.
