啊D的实用性比较好，目前是比较实用的工具，这个版本我自己该过。不错。

学习提高autodyn的必备手册The AUTODYN™ software for non-linear dynamics was first released by Century Dynamics in 1986 with the introduction of AUTODYN-2D. In 1991, AUTODYN-3D, the three-dimensional analog to AUTODYN-2D wa s introduced. The AUTODYN programs are general-purpose engineering software packages that use finite difference, finite volume, and finite element techniques to solve a wide variety of non-linear problems in solid, fluid and gas dynamics. This type of program is sometime s referred to as a “hydrocode”. The phenomena to be studied with such a program can be characterized as highly time dependent with both geometric non-linearities (e.g. large strains and deformations) and material non-linearities (e.g. plasticity, failure, strain-hardening and softening, multiphase equations of state).
