为什么我无论怎么设置步长，计算都是一步就结束呢？

在*control_time 卡片中把第一项的值设为1.0e-3左右，试试。

tempyu

我把*control_time 卡片中的数值改了，步数是多了，但是用ispost打开后运行，却没有显示炸药的爆炸，这是为什么呢？是我建模的问题还是我k文件参数的设置问题？请高手帮帮忙，谢谢啦

"Problem time       =    9.8558E-06"显示你求解的问题只是E-6级别,求解的问题时间本来很短.是当设定求解时间多于问题时间是有利的.

大家一起交流交流吧，我的qq号是16722913。

把你的k文件传上来看看,检查一下起爆点的设置

将D3DLOP改小些
