Flip Fluid Collision Issue (Ocean)

Hello guys! 

 

So I am doing this project for quite a while now where a spaceship is coming out of an ocean. Ocean is a part of flip simulation. I converted my object into a RBD object and gave it some initial velocity in positive Y axis. When I first tried this, it was just for testing purpose. I planned on manually animating the spaceship and using 'use deform geometry' option. However when I use that I don't get the results I expect. The spaceship just go flying through doing very little to the flip. Yes I have proper collision geo for the flip as well.

 

Now I asked Igor on the Facebook Houdini group that how he did his RISE project (vimeo(dot)com/82942136) and he said that he used the geometry as static and animated and used forces to break the fluid sim. Can anyone please elaborate a little more on these forces? I would be very grateful. Please check the link below for a flipbook of the simulation that was done using the 'initial velocity' method. Things pretty much work with this method as well except you lose control over your animation.

Also what is body force with respect to flip fluids and how is that used? 

 

Cheers,

frost
