Hi, I am using the "externalWallHeatFluxTemperature" boundary condition in a transient simulation. I am using openfoam v2012.
I would like to set the T_ambient (Ta) as the mean temperature of a face. The temperature of this face changes during the simulation, so, Ta, should be calculated/updated in every time step.

    {
        type            externalWallHeatFluxTemperature;
        mode            coefficient;
        Ta              constant 300.0; //Should be calculated as the average temperature of a face
        h               constant 10.0;
        . . . 
    }

Do you have any idea of how can I implement such boundary condition?
All the best
Nikos

Hey!


I think the inputValueMapper is a good way to achieve this, but I have never used it so far (I made a post asking about it, no luck so far).


I'll just link this:

Here you can see something slightly similar to what you want to do, but I could not make it work when I tried.


Good luck to you, and please report any progress you make, I would like to know if you manage to figure it out
