编译失败求助

想实现更改每个单元的粘度的功能，于是在laminarTransport的类singlePhaseTransportModel.H中加入了

virtual void crtMyNu(const labelUList& myList,scalar myNu);

目的是为了在simpleFoam里面可以调用laminarTransport.crtMyNu()，输入单元编号的List，和想改成的数值myNu;
然后在Newtonian.H 里加入

        void crtMyNu(const labelUList& myList,scalar myNu)
        {                                                 
                       forAll(myList,i)                                                                                              
                     {                                                                 
                           label cellI=myList[i];                                                                                        
                             this->nu_[cellI]=myNu;
                   }                                                                                                         
     }

实现对nu_的具体修改。
编译libincompressibleTransportModels时没有错误
但是在simpleFOAM.C中加入

laminarTransport.crtMyNu(solidCells,scalar(10000));

后，编译simpleFOAM时报错

make: *** [/home/samuel/OpenFOAM/samuel-v1806/platforms/linux64GccDPInt64Opt/bin/GCSimpleFoam] Error 1

编译错误的原因是什么呢？搞不懂。。

@Samuel-Tu 在编译失败求助中说：

void crtMyNu(const labelUList& myList,scalar myNu)

这句改成 void singlePhaseTransportModel::crtMyNu(const labelUList& myList,scalar myNu) 试试？

Samuel-Tu

@wwzhao 在Newtonian.H里加吗，singlePhaseTransportModel类编译不通过了。

好像发现原因了，Newtonian没有从singlePhaseTransportMode继承，因此如果在singlePhaseTransportMode中定义虚函数是不行的
