kEpsilon和kOmegaSST仍未解决
-
等热流加热圆管流采用kOmegaSST模型在buoyantSimple和rhoSimple均进行了尝试，发散，虽然有类似贴，但仍未解决该问题。采用kEpsilon求解仍然发散，k，epsilon以及omega都采用公式进行估算，但仍然发散，请大家帮忙查看是否是边界问题：
alphat:copy自带算例，湍流prt默认，该如何改？有公式吗？object alphat; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [1 -1 -1 0 0 0 0]; internalField uniform 0; boundaryField { heatflux { type compressible::alphatWallFunction; Prt 0.85; value uniform 0; } outlet { type calculated; value $internalField; } inlet { type calculated; value $internalField; }k
heatflux { type kqRWallFunction; value uniform 0; } outlet { type zeroGradient; } inlet { type fixedValue; value uniform 2.5e-3; }nut：查看资料显示对于不可压缩使用nut，对于可压缩则使用mut，但是使用mut系统报错，{查不到nut}，不太清楚原因，求各位老师指导。
heatflux { type nutUWallFunction; value uniform 0; } outlet { type calculated; value uniform 0; } inlet { type calculated; value uniform 0; }omega
heatflux { type omegaWallFunction; value uniform 0.12; } outlet { type zeroGradient; } inlet { type fixedValue; value uniform 0.12; }p:这里给的是rhoSimple算例
heatflux { type fixedFluxPressure; } outlet { type fixedValue; value uniform 8.8e6; } inlet { type zeroGradient; }T:这个地方有个Ta，一般出现在热辐射中，但是不给Ta就会报错，就给了个常温

heatflux { type noSlip; } outlet { type zeroGradient; } inlet { type flowRateInletVelocity;; massFlowRate 0.001; extrapolateProfile yes; rho rho; rhoInlet 795.55; }此外，还计算了kEpsilon模型，下面给出epsilon
heatflux { type epsilonWallFunction; value uniform 4e-06; } inlet { type fixedValue; value $internalField; } outlet { type zeroGradient; }根据错误log文件，不太确定是否为离散格式存在的问题，下面贴出fvScheme和矩阵求解器

如果网格小，可以把算例处理干净发上来

@东岳 感谢老师回复，这套网格可能稍微大一些，算例中还加有其他的库。我使用相同的设置对二维的平板也进行了计算，除了说除数为0外，下面的原因和求解器有关吗？

这个是你说的二维平板算例是吧？我说的log文件从头开始是指从最最开始的地方，我想看下模型建立过程中有没有别的问题（湍流呀热物性呀之类的）。你用的就是rhoSimpleFoam么，还是自己有改过？
-
@cccrrryyy 热物性库修改过，湍流未做修改，热物性库做过层流验证是可以的。因为是在超算计算，所以错误信息和输出信息是分开的

插值从表格里面做热物性吧？那估计是超临界啥的。算例本身算起来可能是会有点不好收敛。你层流验证的时候好收敛么，还是也很难收敛？如果层流很好收敛但湍流不收敛，那大概率是湍流的边界问题；如果层流本身也很难收敛，那就可以去找别的原因了。其实你可以试试，同样的设置下把热物性换成普通的（理想气体之类的）看看能不能算，这样也能排除一些问题。
单看log文件有两点我觉得值得考虑。1、你设置了pressureControl，限定了压力的最大最小值，你本身的工况是在这个压力范围之内么? 2、这个可能性比较低。你可以把SIMPLE的convergence criteria调小一些，看起来你的速度方程解了1步就收敛了，对线性求解器来说好像太容易了点。
