PetscDualSpaceGetInteriorData#
Get all quadrature points necessary to compute the interior degrees of freedom from this space, as well as the matrix that computes the degrees of freedom from the quadrature values.
Synopsis#
#include "petscfe.h"
PetscErrorCode PetscDualSpaceGetInteriorData(PetscDualSpace sp, PetscQuadrature *intNodes, Mat *intMat)
Input Parameter#
sp - The dualspace
Output Parameters#
intNodes - A
PetscQuadratureobject containing all evaluation points needed to evaluate interior degrees of freedomintMat - A matrix that computes dual space values from point values: size [spdim0 x (npoints * nc)], where spdim0 is the size of the constrained layout (
PetscSectionGetConstrainStorageSize()) of the dual space section, npoints is the number of points in intNodes and nc isPetscDualSpaceGetNumComponents().
Notes#
Degrees of freedom are interior degrees of freedom if they belong (by
PetscDualSpaceGetSection()) to interior points in the references, complementary boundary
degrees of freedom are marked as constrained in the section returned by
PetscDualSpaceGetSection()).
