Hello all together,
I am running an FSI simulation case, where it takes some time, until the coupling becomes relevant i.e. the coupling data doesn’t change very much and has a quite small scale in the beginning.
But after a while, the interaction becomes large and also the coupling data becomes much larger.
It would be beneficial for me, to use an
absolute-conergence-measure in the beginnning (for all coupling data sets), since a
relative-convergence-measure results in too strict absolute thresholds and many iterations are necessary.
On the other hand, it would be beneficial to use a
relative-convergence-measure later in the simulation, since the (initial) absolute measure are hard to fulfill.
suffices=true option isn’t helpful in this case, since both data sets need to be considered independent.
So, is there a way to combine convergence measures by an OR statement?
