Dear fellow COMSOL users,

Does anybody know the implications of the stopping criterion of residual vs. solution-based errors in the segregated solver?

In the model below, If I restart the computation the solution based error keeps going down but the residual error stays high.

So it would seem that it is more beneficial to use the solution-based error then?

Regards,

Gonzalo
