The method was implemented in the simulator of the University of SĂLo Paulo, whose computing core is named â€sDyna”. The model proposed calculates restoration and friction forces between bodies and has a Momentum-Impulse based criterion to reduce numerical issues when the simulation numerical integration has large time-steps. The model was empirically evaluated at the simulator by deck officers, in real-time simulations with pilots and tugmasters. We also ran simulations of that model to compare its performance under different integration time-steps lengths.}, doi = {10.12716/1001.17.04.07}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Maritime Safety, Hydrodynamic Forces, Marine Transportation, Modelling of Maritime Operations, Ship Manoeuvring Simulation, Real Time Simulation (RTS), Deck Operations, Marine Simulators} }
