hyperview 后处理

fwlcl

采用hyperview对ls-dyna进行后处理 对于shell单元的有效塑性应变 一般是看哪个layers的应变？我看选择有很多 默认是Max，什么情况下采用Min  Mid 等等 请指教
帮助里面提到如下，Ls-dyna的shell 单元有layer的定义吗？
Allows you to display a contour for a specified element layer when a layer definition is available for an element.  The contour will be applied to all layers defined in the model.  If an element has no layer definition, as in a mass or solid, the contour is also displayed regardless of which layer is selected.
