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
