unable to float the boat!!
2 Attachment(s)
I am working on tunnel hull speed boat. The wave generated is making the body submerged even with less amplitude of wave. Please help me resolve the problem!!!!:(

ensure your boat flows in still water first in still water - weight could be incorrect.

it doesn't folat it appears submerged. Should I change the position of ship ? serious help required!!!

as I said you need to run with zero in/out flow the case for a few seconds (eg using a timestep of about 0.05s) and monitor vertical motion (sink). if there is no movement then the gravity forces are balanced by the bouyancy forces. if the hull is in a submerged condition after this run, then your hull mass is too high for this hull shape - simple hydrostatics. do the boat tutorial in the Help if this does not understood. ensure you have freed the required DOFs!

I found the solution myself. Actually its got nothing to do with buoyancy. Just go to VOF wave >> head wave >> adjust the point on water level, its simple as that;). Thanks for the sharing your opinion:). Some more questions to come:confused:

well if you had followed my instructions, the boat would rise to the surface of where your flat wave had been incorrectly set, so it is in fact about bouyancy!
