请问各位大侠ALE在实际工程中能做什么分析?多谢!

帮助文件上写:can be used in planar, axisymmetric, and three-dimensional geometries;
我从帮助上下载铜棒冲击刚体板的仿真,做出的结果和文档不一样.而且帮助上下载的也计算不了.
报错为:***ERROR: The requested number of domains cannot be created due to
          restrictions in domain decomposition. The following limitations may
          be helpful in understanding this behavior:
          1. Contact pair requires that the surface nodes be in the same domain.
             In the case of kinematic contact, elements associated with
             the surface facets must also be in the same domain.
          2. An adaptive mesh domain must be contained within a single
             parallel domain. Nodes on the boundary between an adaptive
             mesh domain and a nonadaptive domain must not be shared
             with other parallel domains.
          3. All the nodes involved in a kinematic constraint must
             be in the same domain and must not be shared with other domains.
          4. Nodes associated with beam elements whose center of mass
             does not coincide with the location of the beam node or which
             use the *BEAM ADDED INERTIA option must be within a single domain.
我想可能是下面两方面的错误:
1)contact pair 把铜棒的底面和圆周面都建成一个SURFCE就会报错,用全局接触能算.
2)但用全局接触时ALE就不起什么作用.如下是用全局接触算出的图片

//前不久我做一个卡扣扣入橡胶表带的分析,橡胶单元节点挂住,变形严重.所以就想用ALE能否解决这个问题?
另外,我看论坛中都是用在2D单元的,我用3D单元ALE方法好像没什么作用呢?

公司里面不能上传,呵呵

个人觉得这个应该不需要用ALE
lz 可以重点找找“橡胶单元节点挂住,变形严重”的原因。
