The solid modeling based on STL dare mesh instead of the one based on surface is created to increase morphological comparability. Topological relationship among polygons is reconstructed to modify and Boolean operation. Periodontal ligament, supporting bone and glass fibers are reasonably predigested and constructed in CAD system to reduce the amount of mesh. FEA meshes are generated through splitting method to improve quality of mesh.

By using two different three-dimensional source distri- bution techniques, three-dimensional translating-pulsating source (3DT) and three-dimensional pulsating source (3DP), numerical investigations have been carried out for a high speed monohull ship (RD-200) advancing in oblique waves. The numerical results are compared with experimental values obtained from wave load tests carried out at the SSPA. These extensive test results cover different wave directions at a wide range of wave frequencies.
