Hi guys,

I am learning ship simulations by running the Wigleyhull Tutorial. I enhanced the non-dimensional time-step from 2 to 0.2 (try to see a convergence)
but it can be seen from the picture below that: it looks like I am getting reflections? Or else why do I have waves in front of the boat after large time periods? the time-step size should be the smaller the better but this doesn't occur with large time-step.

Thanks.
