Hi.

This is an interesting question. I don’t remember making this comparison in HEAT myself before (the rise time vs the fall time); however, I would like to clarify few items in case I can make recommendations:

1. How do you measure the fall time? Do you have the shutter step on and step off functions applied to the source, in the same simulation? I think this would be necessary to ensure that with the initial step on, the system reaches steady-state temperature before turning the shutter off to measure the fall time.
2. How do you make your measurements? Specifically, where in the device do you read the measurement from? As you it’s know it’s important to make sure the data from the simulation and measurement correspond to the same region. 
3. Can you share a high level schematic of your device (e.g. the geometry in HEAT)? And outline the boundary condition(s) applied? Boundary conditions in HEAT are critical to the setup and obtained results; I would like to see the setup in case I can make recommendations.
4. Finally, would you be able to share the screenshot of your transient tab in HEAT?

Best regards,
