Development of Numerical Wave Tank Coupled with Structure Analysis Based on FEM

Abstract

This report describes development of the numerical wave tank, called CADMAS-SURF/3D, coupled with the structure analysis based on FEM. The objective of this research is to clarify the stability of this numerical system. In this system, FEM receives the pressure from CADMAS, on the other hand CADMAS uses the porosity changed from displacements of structures. At first, wave paddle model was tried for confirming the stability of variation of porosity. The results of numerical waves were good agreement with the results of experiments. Then, coupling model was tested by using the wall and sea wall model. Through these results, the stability of this numerical system was verified.
