Prediction of ship motions for a Wigley hull using SPH
Prediction of ship motions for a Wigley hull using SPH
This paper outlines a framework that will allow SPH to be used to simulate the motion of a Wigley hull. A number of modifications and novel additions to the open source SPH code SPHysics are proposed to enable this simulation to be carried out. These are a modified wavemaker, a novel non-reflecting open boundary condition and the inclusion of the Wigley hull geometry. The results from two validation test cases are used to verify the capability of these new methods. Firstly a plunger dropped into a wave tank to test the non-reflecting open boundary. Secondly a Wigley hull in regular waves to demonstrate the combination of new techniques applicable to ship motion simulation.

Abstract
This paper outlines a framework that will allow SPH to be used to simulate the motion of a Wigley hull. A number of modifications and novel additions to the open source SPH code SPHysics are proposed to enable this simulation to be carried out. These are a modified wavemaker, a novel non-reflecting open boundary condition and the inclusion of the Wigley hull geometry. The results from two validation test cases are used to verify the capability of these new methods. Firstly a plunger dropped into a wave tank to test the non-reflecting open boundary. Secondly a Wigley hull in regular waves to demonstrate the combination of new techniques applicable to ship motion simulation.
