A hybrid technique using particle and boundary-element methods for wave-body interaction problems

Abstract

In order to expand applicability of particle methods to various practical problems, a hybrid computation method for wave-body interaction problems is developed. The method divides a computation domain into two regions. One is the nonlinear inner region where a particle method is applied. The other is the linear outer region where a boundary element method is applied. These two regions are connected with a boundary called the moving matching boundary. Some simple wave channel problems are computed and the results are validated through a comparison with analytical solution and demonstration of numerical simulations for wave-body interaction problems is made.
