Hello Everyone,

I have a question related to boundary conditions. As we know that we can put different boundary conditions on the inlet and outlet of our geometry.

Is it possible to put power as a boundary condition on the inlet OR on the walls of the geometry? OR If we can derive the power from the existing boundary conditions?

Actually, for my problem, I must give some defined power at the inlet of my geometry, So I want to know the possible way to do that?

Brief description of my problem is here:

I have a pipe from which some fluid is flowing. At the outside wall of a pipe, I have some electrical devices that are touching the pipe from the outside. The power dissipation of those devices are given and I want to know that how much heat will be transferred to the fluid from these devices and what is the temperature of those devices?
