    Why doesn't the Jacobian increase the number of Gauss points required to integrate when using Quadri

    Hi all, For rectangular elements, I understand how the integral for the stiffness matrix ( transpose(B)*c*B ) has a maximum power for eta and xi or two, and thus two gauss points are required. However, when mapping for Quadrilaterial elements the integral gets multiplied by the determinant of...
