I see in Marc that Heat Transfer Coefficient has the unit N/(m* s *K) and Face Film Coefficient N/(m^2 *s*K).
Is the difference in the equation (m^2 at Face Film Coefficient) because of the "thickness of film" so that the equation for face film coefficient has additional m (towards the thickness of film) in the denominator?
In the example e006 Arc Welding Process Simulation, I found a Film Coefficient unit in N/(m^2 *s*K). To be precise: in initial/boundary condition, the value is 0.02.
