Hello, I like to use SNES to solve nonlinear system of equations. For my problem, I have to update some internal variables for computed newtons increments of primary unknowns, before I update residual (right hand side) and Jacobian. I found function SNESSetUpdate which is called at the beginning o every iteration. But I am not sure enough if that function is proper for updating internal variables. Can You advise me if it is right to use internal variables, f.e. increments of plastic strain at gauss points.
