新的湍流模型如何输出yPlus值

小考拉

最近调用一个新写的湍流模型进行计算，发现无法调用yPlus，报错如下：

yPlusLES yPlusLES output:


--> FOAM FATAL ERROR: 

    lookup of LESProperties from objectRegistry region0 successful
    but it is not a LESModel, it is a DMNM

    From function objectRegistry::lookupObject<Type>(const word&) const
    in file /home/lly/OpenFOAM/OpenFOAM-2.3.0/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 181.

根据错误信息，感觉是yPlusLES函数库没有包含这个新的湍流模型DMNM，导致无法调用，但自己又不知道怎么解决

请哪一位朋友能给一些解决的思路或者建议呢？

在新版本里面已经没有这个工具了，通过下面这个命令可以包含，对于你那个，可以重新编译一下y+工具

yPlus1
    {
        type        yPlus;
        libs        ("libfieldFunctionObjects.so");
        ...
    }

感谢老师的回复！问题已经解决，在yPlusLES.C文件里面做对应的修改即可

在最前面加入一行代码

#include "incompressible/LESNonlinear/LESNonlinearModel.H"

后面部分代码作相应修改

const incompressible::LESNonlinearModel& model =
        mesh.lookupObject<incompressible::LESNonlinearModel>("LESProperties");
