Abstract

In order to implement fast grid generation on warhead, warhead's structure was divided into 5 kinds of geometrical characteristics. Key points of generatrix in the section axis were chosen to depict the configuration of each characteristic. Corresponding algorithms and programs of grid generation were established. Those customized programs with C++ programming language can produce grid file applied to AUTODYN or LS-DYNA automatically after getting parameters by reading formatted file, excelled to generic modeling software, TRUEGRID, for example, in modeling ability and modeling efficiency.

Key words： warhead; grid generation; grid file; simulation
