Hi otaku,
I received this explaination from Marven regarding the new Wave Animation gif. So, I hope he won’t mind me sharing it with you and others.

(Dynamic means that additional forces, like wave damping and accelerations are taken
into account too. This is not the case, the animations are static because for each frame the position of the ship is calculated as if the
wave is frozen in time. If an equilibrium is found then the wave moves a bit to the aftship and the process is repeated. It’s a very important
difference. But although it’s a static process it provides some understanding and insight about how the ship behaves.)

So its a visualisation tool to help you in the design process.

To me its the start of the quest for the Holy Grail of marine software, a fully dynamic animated Test Tank on your desk top.
