带薄层的非均匀温度边界条件如何植入？

[刘文凯]

非均匀温度边界条件可以通过codedFixedValue轻松实现，
带壁厚的温度边界条件可以通过externalWallHeatFluxTemperture实现。
如代码所示：

\\非均匀温度边界条件
wall
    {
        type            codedFixedValue;
        name            dummy;
        code
        #{
            const vectorField& Cf = patch().Cf();
            const scalar a0 = 0.1;
            forAll(Cf, faceI)
            {
                const scalar y = Cf[faceI].y();
                (*this)[faceI] = a0*y;
            }
        #};
    }

\\薄壁温度条件
wall
    {
        type                    externalWallHeatFluxTemperature;
        mode                    coefficient;
        h                       uniform 1e10;   
        Ta                      1620;
        thicknessLayers         (0.015);
        kappaLayers             (4);
        kappaMethod             fluidThermo;
        value                   $internalField;
    }

但是，当我想像下面这样编程使Ta为非均匀值时，会报错，即使我使用了codeInclude codeOptions codeLibs之后，仍会报错 ‘patch’ was not declared in this scope，似乎在externalWallHeatFluxTemperature中，无法访问到网格信息。请问各位大佬有解决办法吗？或者有没有别的办法实现带薄壁的非均匀温度边界呢？

‘vectorField’ does not name a type
‘Cf’ was not declared in this scope

Ta              coded;
code
                #{
                    const vectorField& Cf = patch().Cf();
                    const scalar a0 = 0.1;
                    forAll(Cf, faceI)
                    {
                        const scalar y = Cf[faceI].y();
                        (*this)[faceI] = a0*y;
                    }
                #};
