PetscFEComputeTabulation#
Tabulates the basis functions, and perhaps derivatives, at the points provided.
Synopsis#
#include "petscfe.h"
PetscErrorCode PetscFEComputeTabulation(PetscFE fem, PetscInt npoints, const PetscReal points[], PetscInt K, PetscTabulation T)
Not Collective
Input Parameters#
fem - The
PetscFE
objectnpoints - The number of tabulation points
points - The tabulation point coordinates
K - The number of derivatives calculated
T - An existing tabulation object with enough allocated space
Output Parameter#
T - The basis function values and derivatives 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
