The Technology of 3-D Finite Difference Automatic Mesh Generation for Casting
Xu Hong · 2000
On the basis of analyzing date structure of 3 D STL file form,the advantage to construct topological structure has been analyzed.In the mean time,the method to construct topological information has been put forward.Also the calculation method of rapid dividing layers was studied.Therefore the velocity and efficiency of 3 D finite difference mesh generating have been greatly improved.The software which can be adapt to any complicated solid shape were developed and the practicality of the program was proved by application.
