添加湍流模型遇到问题（重发）

[郑澄远]

我用of5.0版本，想添加mykEpsilon模型，用sed语句修改kEpsilon，mykEpsilon.C代码如下

{

    this->nut_.correctBoundaryConditions();
    fv::options::New(this->mesh_).correct(this->nut_);

    BasicTurbulenceModel::correctNut();
}


template<class BasicTurbulenceModel>
tmp<fvScalarMatrix> mykEpsilon<BasicTurbulenceModel>::kSource() const
{
    return tmp<fvScalarMatrix>
    (
        new fvScalarMatrix
        (
            k_,
            dimVolume*this->rho_.dimensions()*k_.dimensions()
            /dimTime
        )
    );
}

用wmake libso编译出现错误

有谁知道是怎么回事吗？

[东岳]

你主要对哪一行代码进行了改动呢？

[郑澄远]

李老师，我按照手册上还没有进行改动，只把kEpsilon改成mykEpsilon,但是编译就报错了，不知道是不是和of5.0有关

[东岳]

就是说你把kEpsilon文件夹下面所有的kEpsilon关键字替换为了mykEpsilon？

[郑澄远]

@东岳 是的，老师

[东岳]

明天我试试
