Default new directMapped BC for the gradient

Hi to all

I m trying to create a new boundary condition from the existent directMapped but instead of recycle the variable value I want to recycle the gradient value. I am simulating the flow in a duct with uniform heat flux at the wall, so I take the velocity profile and recycle it with directMapped but I can not do the same with the temperature because the profile changes. So, the temperature gradient is constant like the velocity, and it is the reason to create a new BC.

Does anyone know how to do that or give any idea?

Thank you very much.
