Abstract
The design of yachts and boats can significantly benefit from simulation-driven design (SDD)
using codes of Computational Fluid Dynamics (CFD). In SDD a large number of virtual prototypes is
in- vestigated numerically for key objectives. In hydro- and aerodynamics objectives often relate
to resistance and lift which govern the performance of both sailing yachts and fast motor boats.
In order to reduce the dimensionality of the design space, i.e., the degrees-of-freedom, a
parametric approach is utilized. For the flow simulation different levels of fidelity are used,
ranging from potential flow analysis to viscous flow simulation solving the RANS equations. Design
examples applying the SDD approach will be presented for both a sailing yacht and a motor boat.
The sailing yacht is a 20m catamaran for worldwide travel and the motor boat is a 6m planing boat
for day cruises. Parametric models for the two vessels will be discussed, comprising the
generation of surfaces and watertight tri-meshes, the latter of which can be fed to the CFD code of
choice. Here SHIPFLOW® and FINE™/Marine were applied in connection with CAESES® which provided
both the shapes and the integration of CFD for SDD. To close the simulation driven design cycle of
the sailing catamaran an appended version of the parametric model with rudders and daggerboard is
used for virtual tank testing. Combining these results with a suitable sail model allows for an
accurate velocity
prediction (VPP) in an early design stage.
