Abstract

A Cartesian grid method is developed for 3D computation of strongly nonlinear wave-body interactions. The CIP (Constrained Interpolation Profile) method (Yabe et al., 2001) is used for multi-phase computation in a Cartesian grid. The free surface is captured by THINC (Tangent of Hyperbola for Interface Capturing, Xiao et al., 2005) scheme, and a newly developed technique is proposed to treat real ships with a complicated shape. The accuracy of the method is shown by a comparable computation with an experiment on a modified Wigley model. A grid convergence test is done on this case. The capability of the method for real ships is demonstrated by a numerical example with a container ship model.
