各位大神我想问一下，我点击bat运算后就出现这个闪退了是什么情况

pandongcsu 兄弟
你的问题很容易解决
两个办法
1：在启动时候coustompreferce里面第一项调大存储设置
2：通过关键字*control—memory设置
希望对你有用

请教楼主 由于小弟是新手 在相关设置上面还很陌生
我主要是作一个锥形尖头戳破薄膜的主题，锥形头视为刚体，
并在Ｚ方向施一负载，小弟在跑结果时，不管怎么调整参数
，尖头都无法戳破薄膜，不知道是材料还元素设置错误，已
上传附件，麻烦楼主指点指点，大家一起来练习～

楼主能不能帮忙给个——SimWe仿真论坛---的邀请码！

敬请版主解答呀，谢谢啦

忘了说一下，模型区域是长宽高分别为60m、60m和8m的长方体区域，因因此，第一个爆炸的药包距离发生异常变化的网格至少有几十米。药包采用二号岩石炸药，每个药包重20kg。

如上图，利用九个药包进行微差爆炸。炸药散布在场地周围。用ls-prepost看结果，发现有些土体区域在炸药还没有爆炸的时候就已经产生了巨大的网格变形和压力，甚至比已经爆炸的土体的变形和压力还要大，而这些区域一般都是远离炸药单元的纯土体啊！理论上不受外力，怎么会有证明强烈的反应呢。不知道大家觉得会是什么原因？困惑中，还望大家答疑解惑k文件较大，发送附件不方便。如果各位还需要些什么信息才能够对我的问题做出解答的话，我再继续发。

谢谢版主指教！
做土体中爆炸分析的时候也遇到个问题。做的是个在一块场地进行的微差爆炸，炸药散布在场地周围，依次爆炸。用ls-prepost看结果，发现有些土体区域在炸药还没有爆炸的时候就已经产生了巨大的网格变形和压力，甚至比已经爆炸的土体的变形和压力还要大，而这些区域一般都是远离炸药单元的纯土体啊！理论上不受外力，怎么会有证明强烈的反应呢。不知道大家觉得会是什么原因？困惑中，还望大家答疑解惑
网格变形和药包位置图如下，第一个药包刚发生爆炸，原处的土体单元就发生较大变形且盈利较大，这是不符合实际的，因为此时其他药包并没有任何变化
