Volume Information Extraction for Complicated Shape and Self-Adaptive Algorithm for Mesh Generation

In the process of computer aided engineering for mechanical parts, it is very important to identify the computational field accurately and efficiently. Based on Layered Manufacturing Technology, a method to build volume model from surface model with self-adaptive subdivision of computational field into discrete grids is presented. This method can be applied to the pretreatment of CAE system, and the result for complicated model works well.
