NUMERICAL MODEL FOR COMPUTING WAVE LOADS ON ARBITRARY SHAPED STRUCTURES

摘要

A Modified Hybrid Element Method (MHEM) for computing wave loads on arbitrary geometric bodies is presented in this paper. The additional unknowns in Mei’s method are eradicated. Water depth varies in space. The MHEM adopts simple functionals to simplify the numerical scheme and the ICCG method to save CPU and storage; thus computing wave loads for a large flow domain or short waves can be carried out on small-sized computers or even microcomputers. Numerical results are compared with analytical solutions and experimental data. Good agreement is observed.
