Constrain a SHIP FEA
Constrain a SHIP FEA
(OP)
Question:
Full Global model of a ship. How can a ship be properly constrained in finite element analysis software. A fixed constraint at any node does not properly simulate hydrostatic buoyancy forces.
How can buoyancy forces be properly modeled in FEA?

water pressure is proportional to depth.

apply balanced load and reactions. this means you have to figure out where the waterline is before you try to determine the internal loads.
or talk to your prof.

it would be somewhat harder to solve for a pitching, heaving, yawing, etc loadcase; but again i'm sure there's a preprocessor for nav archs.
