 * : Maximal number of iterations.
 * : The nonlinear solver starts with the robust Picard algorithm. After some iterations, the algorithm is changed to the Newton algorithm which converges faster but is less robust if the results temporarily diverge (oscillations might occur). This setting sets the number of iterations after which the switch from the Picard to the Newton algorithm is made. Note: the switch is made whatever is reached first, or.
 * : The same as but here a tolerance is set. The tolerance is the norm of the nonlinear residual. If this is reached, the switch from the Picard to the Newton algorithm is made.
 * : The tolerance for the solver to stop. If the error is smaller than the tolerance, the solver run will be is finished. Otherwise the full number of will be performed. In the Elmer output you see in how the error is minimized while the solver is running. In case it does not go down below a certain value that is acceptable but above the current tolerance, you can increase the tolerance.
 * : This is THE most important setting in case the solver does not converge:
