Hi,

I am trying to apply fixedValue BC to some portion of the boundary patch and zeroGradient to remaining patch. I used codedMixed to apply the BC. What I found was, though the code compiles fine, the BC's are not applied to the patch.
I am attaching the code. Can any one please tell me where I made the mistake.

 upperWall
    {
        type            codedMixed;
        refValue        uniform 0;
        refGradient     uniform 0;
        valueFraction   uniform 0;
        

        name    upperWallMixed;  

        code
        #{
            const fvPatch& bp = this->patch();
            const vectorField& cf = bp.Cf();
            scalarField& rValue = this->refValue();
            scalarField& rGrad = this->refGrad();
            scalarField& vFraction = this->valueFraction(); 
            
            forAll(cf, i)
            {
                const scalar x = cf[i].x();                
                if ((x > 0.2) && (x < 0.3))
                {
                    rValue[i] = 10;
                    rGrad[i] = 0.0;
                    vFraction[i] = 1;
                
                }
                rValue[i] = 0;
                rGrad[i] = 0.0;
                vFraction[i] = 0;                
            }
                    
        #};
    }
