Are you sure that determinant of J matrix should be equal to element's volume in the hexahedral (brick) element? I was thinking that this is true only in tetrahedral and triangle elements.

OK, I'll check it...
If the hexahedron is rectangular with dimensions of a x b x c, the determinate of the Jacobian matrix is simply given by 9.54
Hexahedral element ("Brick"). Not fully functioning yet -see GetJMatrixAt. Det[J] should give the elements' volume (not the case right now).
