Sets up a convergence criterion that checks only the norm of the solution update from one iteration to another.
A relative and/or absolute tolerance value can be specified, which is applied to the norm of the whole solution vector, i.e., the entirety of all process variables.
At least one of the relative or absolute tolerance has to be met in order to satisfy this convergence criterion, i.e., the following has to hold (with errors \(e\) and tolerances \(t\)):
\[ e_{\mathrm{abs}} \le t_{\mathrm{abs}} \vee e_{\mathrm{rel}} \le t_{\mathrm{rel}} \]
