Hey everyone!


I am trying to set up a simulation with a cold wall and a hot wall in a square cavity. The hot wall temperature would be regulated by the cold wall temperature (where a negative flux is applied). For that, I saw that OpenFoam v2112 had inputValueMapper to create dependent boundary conditions :

My hot wall boundary condition looks like this:

hot_wall
    {
        type    uniformFixedValue;

        value
        {
            type            inputValueMapper;                                  
            mode            function;                                          
            
            function                                                           
            {
                // Here we retrieve data from another FO (its the x-value)
                type                 functionObjectValue;   

                // The name of the FO                               
                functionObject       averageSurfaceTemperature;

                // The result used for x         
                functionObjectResult average(cold_wall,T);
                         
                defaultValue         200;
            };                                                                  
            
            
            value                                                              
            {                                                                  
                type            table;                                         
                values
                (
                    (273.15  293.15)
                    (283.15  283.15)
                );
            };                                                                   
        }
    }

So my hope was that the hot wall would be between 283.15 and 293.15 Kelvins depending on how cold the other wall gets.


But I get this error:

--> FOAM FATAL IO ERROR: (openfoam-2112 patch=220610)
Missing or invalid PatchFunction1 entry: uniformValue

I haven't found any resource about this inputValuemapper that looks quite powerful, other than the link I shared. Can anyone help me on this, or provide some information? Thanks for the help!
