Hi Guys,

I need help, I have ran a simulation on vessel in calm water. there is a problem with my solution. I ran 3 refinement grid, coarse, medium and fine. The solution for coarse grid looks ok to me, medium looks kind of weird too, but the problem was on fine grid. There is a weird kind of wave form in the domain, looks like it genarate wave at the inlet boundary.I am not sure what is the problem. can someone help me and explain what is the problem there and how to fix it. thanks

*I attached the solution image
