Question about ANSYS heat transfer problems with convection
Question about ANSYS heat transfer problems with convection
(OP)
Folks:
I used an FEA program years ago for thermal problems where, whenever a problem included convection, the user was required to provide a convection coefficient "h" in a convective boundary condition h(Tw-T∞) for a hot wall and cool fluid. This applied to natural convection problems and forced convection problems. Is it still true with FEA programs like ANSYS that this constant "h" must be provided by the analyst?
TIA for your feedback.

The reason you do not need to provide a convection coefficient is that FLUENT is a finite difference code, not an FEA code. If you're using the code one would think you would know something that basic.
