PetscDualSpaceApplyFVM#
Apply a functional from the dual space basis to an input function by assuming a point evaluation functional at the cell centroid.
Synopsis#
#include "petscfe.h"
PetscErrorCode PetscDualSpaceApplyFVM(PetscDualSpace sp, PetscInt f, PetscReal time, PetscFVCellGeom *cgeom, PetscInt Nc, PetscErrorCode (*func)(PetscInt, PetscReal, const PetscReal[], PetscInt, PetscScalar *, void *), void *ctx, PetscScalar *value)
Input Parameters#
sp - The
PetscDualSpace
objectf - The basis functional index
time - The time
cgeom - A context with geometric information for this cell, we currently just use the centroid
Nc - The number of components for the function
func - The input function
ctx - A context for the function
Output Parameter#
value - The output value (scalar)
Calling Sequence of func
#
PetscErrorCode func(PetscInt dim, PetscReal time, const PetscReal x[], PetscInt numComponents, PetscScalar values[], void *ctx)
Note#
The idea is to evaluate the functional as an integral \( n(f) = \int dx n(x) . f(x)\) where both n and f have Nc components.
