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