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
