Because of recent developments of mathematical and physical arithmetic in improvement of analytical accuracy, e.g., spectral/hp element methods, the finite element method is of further importance for making progress in computer fluid dynamics. In application of this method to large scale engineering problems with complex boundaries, a first difficulty is automatic mesh generation. The present paper describes a method of two-dimensional finite element mesh generation, developed with a concept of the generation front and included in CATWAVES - Wave Analysis System: concretely, with the aid of a simple example for coastal wave-deformation, they are the ways to divide and specify a region of analysis, to generate mesh in each subregion under distribution of internal nodes, and finally to interpolate the nodal water depth. In addition, examples of particular mesh generation are demonstrated to model regions composed of coastal structures. The schemes of present mesh generation are found to be effective and reliable, and are available to the other fields of problems.
