摘要
利用有限元与边界元耦合法对三维无界区域中直立圆柱所受的波浪力进行计算,把整个求解区域分成内域和外域两部分,在内域采用有限元法,对外域采用边界元法,数值计算的结果与理论解吻合良好,表明该方法有效.
The finite and boundary element coupling method is utilized to calculate the wave force acting on a vertical circular cylinder in the three-dimensional unbounded region. The whole region is divided into two parts, the inner domain and the outer domain. In the inner domain, the finite element method is adopted and in the outer domain the boundary element method is used to calculate the result of the problem. The numerical results are consistent with the theoretical values very well, which shows the effectiveness of the devised method.
