Time accurate CFD solver for ship motions and added resistance.

Flow solver for computing ship motions in waves.

It is a time accurate fully nonlinear boundary element method which can be used to compute ship motions and added resistance in regular and irregular waves as well as wave resistance, sinkage and trim in calm water. Typical results are time series and response amplitude operators. We believe that the method will be a useful tool for ship designers with better accuracy than traditional potential flow methods while at the same time being faster than the available RANS methods.

Viscous flow solver for ship resistance and propeller hull interaction.

Advanced viscous flow solver

Detailed predictions of the wake are required for design of propellers and for looking at the interaction with appendages. This calls for an advanced viscous flow method. SHIPFLOW uses an unconventional technique, which combines a very stable numerical scheme with other advanced features, such as a turbulence model especially developed for ship stern flow and a novel gridding technique. The viscous flow RANS solver, XCHAP, can be used for computing the double model solution or the viscous free surface. Depending on the type of ship, speed and what effects are studied the user can choose which modules to use. To enhance the stability of the solution the differential equations are discretized considering the magnitude and direction of the flow of information and non-physical fluctuations in the solution are suppressed. Full scale computations using this technique can be made without problems. The default turbulence model is of the algebraic stress type (EASM), and has proven to be especially accurate for stern flow predictions.
