Abstract

This paper describes a novel methodology, using the open source SPH code SPHysics, that is capable of simulating the motion of a Wigley hull in a wave tank. To achieve this capability a number of modifications made and new features added. These are a Wigley hull geometry modelled as a floating body, a new inflow condition based on the Airy wave theory and a two-part outflow condition that acts as a non-reflecting open boundary. To verify the capability of the new methods a series of test cases have been conducted. These are 2D and 3D wave tank simulations to test the inflow and outflow conditions and finally a Wigley hull is simulated in a wave tank to test all of the new methods simultaneously.
