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
