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
Note: The calling sequence for the callback func is given by
func(PetscInt dim, PetscReal time, const PetscReal x[],
PetscInt numComponents, PetscScalar values[], void *ctx)
