Mathematical modeling

Single and multi-objective numerical optimization

The geometry of the ship (or portions of it) is automatically changed to improve performance, using one or more user-defined objective functions and/or more load conditions and/or more speed values.

In calm water

  • Total resistance;
  • Wave resistance;
  • Pressure distribution prescribed on part of the vessel;
  • Dynamic attitude of the ship.

In rough sea

  • Peaks of response operator (heave, pitch) in waves for different sea states;
  • Added resistance in waves, for different sea states;
  • Vertical acceleration and speed at a given number of stations on the ship (e.g. flight deck, bridge, etc.).

Sea-keeping predictions for displacement vessels

With three-dimensional potential model, for different ship operating conditions (displacement, speed, sea state) and different directions of sea wave propagation.

  • Response operator on ship motions;
  • Hydrodynamic loads on the hull;
  • Acceleration at different points of the hull;
  • Prediction of water on the deck and superstructures loads assessment;
  • Prediction of impacts of the hull during large amplitude motions and assessment of resulting loads.

Prediction of hydrodynamic performance of the vessel and of the main features of the flow around it

With unsteady RANSE solver for various operating conditions.

  • Total resistance;
  • Pressure distributions and hydrodynamic loads on the hull;
  • Streamlines pattern around the hull;
  • Axial wake and speed distribution in the area of the propeller disk;
  • Dynamic attitude of the ship;
  • Static and dynamic maneuvering tests (PMM) and prediction of their characteristics.
