fem | - The PetscFE object | |
npoints | - 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 |
T | - The basis function values and derivatives at tabulation points |
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
