Can FEATool Multiphysics simulate nonlinear problems?

We are interested in nonlinear FEA solvers such as those needed for geometrically nonlinear mechanical problems or multiphysics problems that are coupled with these (thermomechanical, thermal-fluid).

FEATool solves non-linear PDEs with either (damped) Picard fixed-point iterations, or given a Jacobian the Newton method. Using FEniCS also offers some more non-linear solver options.
