Description

In this paper the authors apply two types of adaptive mesh refinement procedure to a transverse ring of a tanker. One is the method to generate boundary fitted coordinate systems using biharmonics on appropreate boundary conditions, which are adaptively optimized for each problem. The other is the h-method, in which a quadrilateral element exposed to high error estimate is simply divided into four quadrilateral elements. We compare effciency of various meshes created by the two methods and investigate advantage and disadvantage of each method. It is shown that these methods are effective and practical when they are applied to ship structure analysis.
