Hydrostatics and stability

Hydrostatic equilibrium

The hydrostatic equilibrium of a floating body can be solved within FRyDoM by mainly two methods. The first method is based on the direct time domain decay simulation of the body motions with proper damping models, or relaxation (zeroing the linear and angular velocities). The second methods relies on a Newton-Raphson solver, which solves iteratively the hydrostatic equilibrium, by computing the stiffness matrix on the body clipped mesh.
