PETSc version 3.15.5
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)
