simulate a floating object without modeling fluid

Mahdi_O

Hello everyone

I want to model a floating iceberg without modeling the water. I want to float it by applying gravity as a body surface and buoyancy as a surface force (as a function of depth). Does anybody have any idea about how it is possible to LS-DYNA can understand the equilibrium point of a floating object (because for applying pressure as a function of depth, the first step is to identify the water surface)? And how to apply pressure as a function of depth?

I appreciated if you can share with me any tutorial similar to this problem with me.

Thanks
