PetscFEGetCellTabulation#
Returns the tabulation of the basis functions at the quadrature points on the reference cell
Synopsis#
#include "petscfe.h" 
PetscErrorCode PetscFEGetCellTabulation(PetscFE fem, PetscInt k, PetscTabulation *T)
Not Collective
Input Parameters#
- fem - The - PetscFEobject
- k - The highest derivative we need to tabulate, very often 1 
Output Parameter#
- T - The basis function values and derivatives 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
