PetscDualSpaceCreateSum

Create a finite element dual basis that is the sum of other dual bases

Synopsis

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceCreateSum(PetscInt numSubspaces, const PetscDualSpace subspaces[], PetscBool concatenate, PetscDualSpace *sumSpace)

Collective

Input Parameters

• numSubspaces - the number of spaces that will be added together

• subspaces - an array of length numSubspaces of spaces

• concatenate - if PETSC_FALSE, the sum-space has the same components as the individual dual spaces (PetscDualSpaceGetNumComponents()); if PETSC_TRUE, the individual components are concatenated to create a dual space with more components

Output Parameter

• sumSpace - a PetscDualSpace of type PETSCDUALSPACESUM
