Notes:
A seamless analysis of IT-related products, such as cellular phone, LCD monitor and notePC etc., which are thin and complex geometry is one of great concerns in product design. However,there is a considerable amount of gap between the industrial application and fundamental academicstudies due to a time consuming detailed mesh generation. In order to settle the bottleneck, an automesh generation program based on a modified grid-based approach is proposed in this paper. At first,base mesh and skin mesh were generated using informations on entities which extracted from anIGES (Initial Graphics Exchange Specification) file. Secondly, a provisional core mesh with a roughboundary geometry was constructed by superimposing the skin mesh into the base mesh generatedfrom CAD model. And then, positions of boundary nodes were redistributed to delineate exactgeometry of the provisional mesh. Finally, good qualified meshes were constructed by moving thepositions of the nodes and splitting elements along boundary edges. In conclusion, it is anticipatedthat the developed program can be used as a promising pre-processor for static or dynamic analysis ofvarious IT-related products
