	B	- The basis function values at quadrature points
	D	- The basis function derivatives at quadrature points
	H	- The basis function second derivatives at quadrature points

B[(p*pdim + i)*Nc + c] is the value at point p for basis function i and component c

D[((p*pdim + i)*Nc + c)*dim + d] is the derivative value at point p for basis function i, component c, in direction d

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
