PetscFVGetCellTabulation
Returns the tabulation of the basis functions at the quadrature points
Synopsis
#include "petscfv.h"
PetscErrorCode PetscFVGetCellTabulation(PetscFV fvm, PetscTabulation *T)
Not collective
Input Parameter
fvm -The PetscFV object
Output Parameter
T -The basis function values and derviatives at quadrature points
Note
T->T[0] = B[(p*pdim + i)*Nc + c] is the value at point p for basis function i and component c
T->T[1] = D[((p*pdim + i)*Nc + c)*dim + d] is the derivative value at point p for basis function i, component c, in direction d
T->T[2] = H[(((p*pdim + i)*Nc + c)*dim + d)*dim + e] is the value at point p for basis function i, component c, in directions d and e
