我在使用subsetMesh命令时，出现以下提示，温度场无法正常设置，有哪位朋友遇到过吗
Subsetting volScalarField (T--> FOAM Warning :

@李东岳 李老师，请教一下，如果出现了比较大的负值该怎样处理呢，我用interFoam计算，后面min（aipha.water)到了负的0.3左右，然后发散了，请问这个怎样可以解决呢

@学流体的小明 好的，谢谢

interFoam求解器计算到这里就发散了，有没有大神帮忙看一下是什么问题

@xuanze 3374769460@qq.com

@Emrys 所以应该细化网格吗

各位老师，有没有什么代码可以计算多个区域内（比如几个确定直径和球心的球形区域）的网格数

@Emrys 为什么速度小了不可以呢

@Emrys 速度放大可以的，小了就不行

各位大神，我想请教一下，在interfoam中，我想设置入口为速度条件，并且入口处液态水相分数为1，算到后面相分数小于0，发散，但是设置压力边界条件不会出现这样的问题。请问有人可以指点一下吗

@xuanze 可以呀，欢迎

@李东岳 感谢回复
李老师，如果是将这部分命名，也就是放进一个cellZone里面，不删除，这样有啥好办法吗

各位大神，我最近在做多孔介质的课题，我是先画了背景网格，然后用toposet将固体域网格删除，留下流体域网格进行两相流计算。我想请教一下大家有没有好的办法统计孔径。
