Version12 vs Version14
 

Hello Friends
I have done some simulations about wave generated by ship by version 12.1 and compared the results for wave height, drag and vertical forces with the experimental data. now I have to switch to use of version 14.0. I am trying to simulate some conditions which I have done previosly in v12.1
Unfortunately, the simulation diverge after couple iterations, while I use same setting that I have used in v12.1

It would be appreciated if you can give any suggestion and make me able to tackle it.
