Hi,

I am trying to simulate flow around a ship hull. I get good wave patern when I run the simulate without rigid body motion using DFBI translation and rotation activation (for trim and sinkage calculation). But when I activate rigid body motion, the converged wave patern formed earlier gets distorted and drag, trim and sinkage values starts to oscillate. I ran the simulation till 50 sec and there is no convergence of drag, trim and sinkage.

Kindly help.
Thanks

Manoj
