I'm using FEMSystem for a problem, and I'm getting solid quadratic convergence with the Newton solver. However, when I turn on the finite difference jacobian check using "verify_analytic_jacobians = 1.e-6" it reports an error: "Relative error 0.133922 detected in analytic jacobian on element 0!"
I expected the code to pass this test, given that I'm getting good convergence behavior. So before I do too much more bug-hunting, I just wanted to check if there's a chance that I might be getting a "false positive" with the finite difference jacobian check?
