A technique for generating a medial surface model-that is used to transform a thin structure into a medial surface model for FEM-was developed. This technique can reduce the workload in generating a medial surface model for a thin structure model. The technique has two features. First, the medial surface model can he generated from a solid model including rib because the rib faces can be recognized by adjacency-relation graph of solid-model. Second, the shape of the medial-surface model can he controlled according to the analysis type because the shape of medial-surface model can be controlled by user interactive operations. Furthermore, the developed technique was applied to the generation of medial surface models of bracket and cellular phone cover and the effectiveness of this technique was confirmed.
