Abstract: Automatic mesh generation programs are developed with solid element and shell element in FEM for the analysis of orbiting scroll which has some general applications, the division of the meshes, and the calculations of stress and deformation within the orbiting scroll. The advantages of the two types of element are summarized and a conclusion is presented. These software can be applied to design and development of the scroll compressors.

Key words: Deformation, Efficiency, Finite element method, Scroll compressor, Stress
