建立了近岸波浪折射-绕射-破波耗散的有限元数值模式。采用的有限元方法为改进的混合元法,其中外域开边界条件得到改进,内域有限元为伽廖金有限元。用理论解检验了所建立的数值模式,并将该模式应用到一个模型港湾。
The finite element numerical model for the near-shore wave refraction-diffraction-wave dissipation is established. The finite element method used is an improved mixed element method, in which the outer boundary conditions are improved and the inner finite element is the Galois finite element. The theoretical model is used to test the established numerical model and apply the model to a model harbor.
