关于模型运算时间特别长的问题

bibisky

做了一个叠层板的轴压，最上面和最下面是超厚的钢板，模拟刚体用的，

模型里面有些层是橡胶；

但是算一次居然要7个小时多？

是不是和 Nummrg 命令有关系？
我把每层之间用的Nummrg连接起来的，

还是其他哪些地方有问题？

大家帮忙看一下，谢谢啦

计算时间的长短好像只与单元个数有关，划分的单元越多，计算时间越长。

王兆喜

好像不是这么简单的啊

xiaaiyin

七个小时不算长时间吧，我的模型动不动就得16个小时往上，最后调调参数都很费劲。可以减少单元，换合适求解器，或者换本构模型，或找个工作站、服务器之类的算算应该可以减少时间
