Simlab Transient Heat Transfer Analysis

Hello,

 

I am studying the assembly of the brake system to evaluate the temperatures over time, of the system. I have defined inital temperatures, thermal contacts between the assembly and all the relevant heat inputs in the disc brake and the brake pads surfaces.. Now i am stuck in defining the convection loads.. If i use a constant convenction film coefficient the results are fine and admissable, but i open the option Time dependent load, and then i start filling the table points the the time and the amplitude of the load. Does this amplitude acts upon the film coefficient or upon the film temperature. I want it to act on the film coefficient and i decided to use the value 1 on the film coefficient and use the table as a scale factor. The values stoped making sense when i did that. Can anybody help me with that?

 

I am using Simlab 2019.2

 

On the image below you can se me using the film coefficient of 5e-6, because my units are W/mm^2.C for the coefficient to give correct values. In the table i used the scale factor compared to the defined value. Does that scale factor acts on the temperature or film coefficient?
