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

史浩

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！

@史浩您好，请问对于自适应网格的设置讲解有什么资料可以帮助我学习参数设置的吗
