Hi,
Is there a reference or formula for the Jacobian calculation? I have a shell mesh, and I'm trying to reshape the shell by modifying elements with negative Jacobians. It would be handy to be able to calc. the negative Jacobian on my own, and modify the mesh locally.
Ie, given four points (xi,yi,zi, i=1,4) that define a shell element, and a shell thickness t, how does FEBio calculate the Jacobian? Is it typically done at every Gauss point?
Thanks,
-Christian
