Abstract

In the FEA(Finite Element Analysis) for ships, it is a practical method to design geometry model in CAD software,complete FEA in general CAE software. which needs discretize the continuous model in CAD to FEM(Finite Element Model), itincludes automatic mesh generation, mesh mending and mesh refinement. According to the FEA for ships, common automatic meshgeneration methods are introduced in this paper, and a new automatic mesh generation algorithm based on paving is presented bywhich the ship CAD model is auto meshed. Then the mesh mending and mesh refinement are also discussed.
