Surface film coefficient

Hello,

 

I am performing a heat transfer simulation on acuSolve and I want to get the convection coefficient. I suppose that the surface film coefficient refers to that, but how is it calculated? I know that in ansys fluent is calculated this way: ae501fdb-fa00-4425-a374-a8d500e95ac9_computing-heat-transfer-coefficient-wallfunction.jpg?width=690&upscale=false 

Thank you

    Please review the 'AcuTherm' section in the AcuSolve Help System - under AcuSolve Programs Reference Manual > Post-Processing Programs > AcuTherm.  The surface_film_coefficient is essentially Method 3 on that page, using the default of Y+ = 100.  This is dependent only on the turbulent flow solution.
