Boundary Condition for heat flux changing by time
 
Hi,

I want to model the heat transfer from a surface to the surrounding air. I found the wallHeatTransfer BC, but I need the heat flux to change by time. I tried to mix this BC with uniformFixedValue and a uniformValue table, but this won't work.

I have sufficient information on the surface temperature by time and the heat flux by time, I only need to give this to OpenFOAM.

Does anyone have an idea - besides installing groovyBC, which is not so easy in my case - how I can implement this boundary condition?

Thanks a lot!

Best regards,

Robert
