Hello, I am wondering if anybody has also found that the inverse of the Jacobian from FE Values, with MappingQGeneric does not satisfy the Geometric Conservation Law (GCL), in the sense of:

Kopriva, David A. "Metric identities and the discontinuous spectral element method on curvilinear meshes." *Journal of Scientific Computing* 26.3 (2006): 301. on curvilinear elements/manifolds in 3D. That is: \frac{\partial }{\partial \hat{x}_1} *det(J)* \frac{\partial \hat{x}_1 }{\partial x_1} + \frac{\partial }{\partial \hat{x}_2} *det(J)* \frac{\partial \hat{x}_2}{\partial x} + \frac{\partial }{\partial \hat{x}_3} * det(J)*\frac{\partial \hat{x}_3 }{\partial x_1} != 0 (GCL says it should =0, similarly for x_2 and x_3) If so or if not, also, has anybody found a remedy to have the inverse of the Jacobian from FE Values with MappingQGeneric to satisfy the GCL.
