李老师,怎么用到h0中的数据呢,报了这个错误
    outlet
    {
        type            codedFixedValue;
        value           uniform 0.01; //default value
        redirectType    linearTBC; //name of new BC type
        code
        #{
        const vectorField& Cf = patch().Cf(); // get face center coordinate;
        scalarField& h = *this;
        forAll(Cf,faceI)
        {
        	h[faceI] = 0.01-h0[faceI]; 
        }
        #};
