Question about ANSYS heat transfer problems with convection

[Tunalover]

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(T[sub]w[/sub]-T[sub]∞[/sub]) 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.

In Ansys Fluent you do not need to provide a convection coefficient. You do need to specify other inputs that would affect the rate of heat transfer like materials, boundary conditions, ambient temp/pressure, flow rates, power dissipation, etc.

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.

You asked a yes/no question, I answered it with a no. Are you now berating the form that answer took?

You have my apologies.
