PetscDualSpaceApplyDefault#
Apply a functional from the dual space basis to an input function by assuming a point evaluation functional.
Synopsis#
#include "petscfe.h" 
PetscErrorCode PetscDualSpaceApplyDefault(PetscDualSpace sp, PetscInt f, PetscReal time, PetscFEGeom *cgeom, PetscInt Nc, PetscErrorCode (*func)(PetscInt, PetscReal, const PetscReal[], PetscInt, PetscScalar *, void *), void *ctx, PetscScalar *value)
Input Parameters#
- sp - The - PetscDualSpaceobject
- 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) 
- Nc - The number of components for the function 
- func - The input function 
- ctx - A context for the function 
Output Parameter#
- value - The output value 
Calling sequence#
   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.
