fem -The PetscFE object

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

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

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

Hf[(((f*pdim + i)*Nc + c)*dim + d)*dim + e] is the value at point f for basis function i, component c, in directions d and e
