@wangfei9088 非常感谢

请教各位大佬，我用欧拉拉格朗日计算一个二维矩形区域内均匀分布空气和小液滴的两相燃烧问题，是不是要考虑Z方向厚度？给定Z方向厚度才能计算出具体气体质量，然后根据当量比计算出液体质量，进而根据粒子直径计算具体粒子数目。

您好，请教您一个问题，您知道reactingCloudProperties字典文件中RanzMarshallCoeffs下的BirdCorrection开和关有啥区别吗

有做爆轰的大佬吗，请教如何得到处理出如下的胞格图

大家好，我参考openfoam自带的求解器，在求解器中添加自适应网格的功能。我的算例网格总数是50000，运行算例的时候，遇到下面的错误

以下是reactMinMax.H 17-30行

17    const label tautableDim = 3; 
18  
19    forAll(p,i)
20    {
21	List<scalar> lookupCoordinates(tautableDim,0.0);
22		lookupCoordinates[0]=fH[i];
23		lookupCoordinates[1]=pHI[i];		 
24		lookupCoordinates[2]=THI[i];
25
26    	const List<scalar> &LOG_t_ign_temp = tignTable.lookUpBounded(lookupCoordinates,false);
27	tIgnHI[i] = min(max(1e-14,pow(10,LOG_t_ign_temp[0])),1e9);
28	
29   }
30    tIgnHI.correctBoundaryConditions();

请教大家问题在哪呢

@东岳 东岳老师您好，我用的openfoam版本是2.1.1,好像不支持监测location,只能记录最大值和最小值。有其他办法吗

如何在计算过程中监测记录压力最高点的移动轨迹，或者计算结束后如何在后处理过程中得到压力最高点的移动轨迹呢？有人知道吗
