PetscFEGetFaceTabulation
Returns the tabulation of the basis functions at the face centroid points
Synopsis
#include "petscfe.h"
PetscErrorCode PetscFEGetFaceCentroidTabulation(PetscFE fem, PetscReal **F)
Not collective
Input Parameter
fem -The PetscFE object
Output Parameters
| B | - The basis function values at face centroid points
|
| D | - The basis function derivatives at face centroid points
|
| H | - The basis function second derivatives at face centroid points
|
Note
Bf[(f*pdim + i)*Nc + c] is the value at point f for basis function i and component c
Df[((f*pdim + i)*Nc + c)*dim + d] is the derivative value at point f for basis function i, component c, in direction d
Hf[(((f*pdim + i)*Nc + c)*dim + d)*dim + e] is the value at point f for basis function i, component c, in directions d and e
