Hi there, I have a similar coordinate transformation question. I try to map x'=2x from the original coordinate system, x, y, z, and keep invariant in y and z direction. The Jacobian matrix is
J=diag(2,1,1) with det(J)=2. In this case, we have J * J' / det(J) = diag(2,0.5,0.5). The original \epsilon is diag(1,1,1), so the new \epsilon is supposed to be diag(2,0.5,0.5). However, meep cannot give me a result. I am wondering that if there any misunderstanding happens on me? Please give me a hand. Thank you so much.
