Abaqus boundary condition help(ship hull and sea water)
Abaqus boundary condition help(ship hull and sea water)
(OP)
Hi everyone
I am trying to perform some FEA sumulation using abaqus on a ship hull. I am having doubts concerning the necessary boundary conditions since its being simulated in still water. Could someone tell me what the best(closest to reality) boundary conditions i can apply to the hull to simulate sea water, or whether there is a way in abaqus to actually do that. I have found something about creating a coupled Eularian-Lagrangian model, can i apply that to my situation.
I have attachewd my model if anyone is interested to have a look
thank you

thanks for the reply. Yes, I would have to apply a water pressure distribution for the draft...but i dont really get it, there should not be no boudary condition since the hull is being supported by sea water. I am actually simulating the hull under its own gravity for deflections,,,

Would it be accurate if you use the weight of the structure itself as the force and use the projected area (projected down) to arrive at pressure at all the nodes on the hull and use these two as the boundary conditions??
