PETSc version 3.15.5
PetscFVCreateTabulation
Tabulates the basis functions, and perhaps derivatives, at the points provided. 
Synopsis
#include "petscfv.h" 
PetscErrorCode PetscFVCreateTabulation(PetscFV fvm, PetscInt nrepl, PetscInt npoints, const PetscReal points[], PetscInt K, PetscTabulation *T)
Not collective
Input Parameters
|  | fvm | - The PetscFV object | 
|  | nrepl | - The number of replicas | 
|  | npoints | - The number of tabulation points in a replica | 
|  | points | - The tabulation point coordinates | 
|  | K | - The order of derivative to tabulate | 
Output Parameter
|  | T | - The basis function values and derviative at tabulation 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
