OpenFoam中的溃坝算例加入自适应网格计算一定时间步后出现的问题

云翳的黄昏

请问各位大佬有没有曾经遇到过算例计算过程中提示“浮点数例外 (核心已转储)”
，谢谢帮忙解答！
我最近在学习interFOAM求解器相关知识，目前向使用interFOAM求解器加上自适应网格计算两相流问题，在利用OpenFoam自带算例修改无报错后，开始利用interDyMFoam进行求解。但何运算基本在0.3s附近出现下图中的错误中断（of2.3.1和of7中都出现了该报错）
![0_1596110438484_2020-07-30 19-57-10屏幕截图.png](正在上传 100%)
![0_1596110989816_2020-07-30 20-06-37屏幕截图.png](正在上传 100%)
而且还有一个问题，但何运行计算到0.3s附近出现该错误，双核并行0.1s，四个核时亦不就中断了。无自适应时算例能正常计算。
麻烦各位大哥有知道y原因的帮忙回答一下，谢谢!

这个应该是自适应在二维网格下计算过程中出现的问题，后来尝试把二维算例改成三维算例。就不会出现计算过程中断的问题了。因为我目前还在学习，具体原因尚不清楚。有对这一部分深入研究的可以补充，我也学习一下，谢谢！也帮助我们这些初级学习者快速入门，尽快排除bug

这个主要问题是OpenFOAM自带的AMR是基于三维网格的，二维网格就会报错。关于2D自适应网格的资料看这里

@史浩恩恩，谢谢大哥！我好好学习一下，有问题再请教！
