就波浪与结构物相互作用问题 ,应用 B-样条函数对物体表面上的速度势进行了数值离散。物体表面的控制参数通过最小二乘原理确定 ,速度势控制参数通过 Galerkin理论确定。本理论给出的速度势及其导数在整个光滑物面上都是连续的。采用此种方法所计算的数值解十分准确 ,并且收敛得很快。 For the interaction between wave and structure, B-spline function is used to discretize the velocity potential on the surface of the object. The control parameters of the object surface are determined by the principle of least squares, and the velocity potential control parameters are determined by the Galerkin theory. The velocity potential given by this theory and its derivatives are continuous over the entire smooth surface. The numerical solution calculated by this method is very accurate and converges very fast.
