Study of ship deformation accumulation for a long time is of practical significance. According to the initial-boundary value problem of the deformation of the ship, large deviation theory gives the deformation time series convergence theorem, which deduces the convergence rate formula of discrete deformation. The convergence speed of the actual example is attached.
The fluid-solid coupling hydrodynamics parallel model of large ship is built based on VOSS mapping theory. The VOSS algorithm of large ship's wave is given, and the control equation and initial boundary conditions are derived from fluid hydrodynamic theory and solid elastic theory. The numerical results show the VOSS transfer of ship fluid-solid coupling wave is not same as coming see wave.
