ShipMo3D Version 3.0 User Manual for Creating Ship Models

Kevin McTaggart

Abstract

Abstract : ShipMo3D is an object-oriented library with associated user applications for predictingship motions in calm water and in waves. This report serves as a user manualfor creating ship models using ShipMo3D Version 3.0. A companion report servesas a user manual for predicting ship motions in the time and frequency domains.Version 3 of ShipMo3D introduces modeling of sloshing tanks and U-tube tanks.Several ShipMo3D applications are used for creating a ship. SM3DPanelHull createsa paneled representation of the wet and dry portions of the ship hull. SM3DRadDifcomputes radiation and diffraction forces acting on the wet hull using a boundaryelement method. SM3DPanelSloshTank creates a paneled representation of asloshing tank, such as a tank containing liquid cargo or a roll stabilization tank.SM3DRadSloshTank computes sloshing forces arising from motions in the frequencydomain. SM3DBuildShip creates a model of the ship that can be used for ship motionpredictions in either the frequency domain or time domain.
