PetscDualSpaceApply#

Apply a functional from the dual space basis to an input function

Synopsis#

#include "petscfe.h" 
PetscErrorCode PetscDualSpaceApply(PetscDualSpace sp, PetscInt f, PetscReal time, PetscFEGeom *cgeom, PetscInt numComp, PetscErrorCode (*func)(PetscInt, PetscReal, const PetscReal[], PetscInt, PetscScalar *, void *), void *ctx, PetscScalar *value)

Input Parameters#

  • sp - The PetscDualSpace object

  • f - The basis functional index

  • time - The time

  • cgeom - A context with geometric information for this cell, we use v0 (the initial vertex) and J (the Jacobian) (or evaluated at the coordinates of the functional)

  • numComp - The number of components for the function

  • func - The input function

  • ctx - A context for the function

Output Parameter#

  • value - numComp output values

Calling Sequence of func#
