Dear all

Hi, I have problems dealing with side ship launching performing in NUMECA using overset grid. I attach the arrangement I set up according to real case. For this time being I consider non-viscous flow using about 2 million grid to simulate the motion of the vessel at first touching water till it reaches equilibrium position

I set the slipway as a solid boundary however the ship & overset domain just move down and going out of background domain, how can I solve it.?
is there anyone succeed using overset grid.?

Thank you
