Calculate time derivative of a variable that is stored by the Previous Solution

I read and followed the BLOG"Using the Previous Solution Operator in Transient Modeling". However, I encountered an issue about this approach when I was trying to calculate the time derivative of the maximum temperature. COMSOL reminded me failed to find consistent initial values. Could you please provide me a method to calculate the rate of the temperature?
Thank you for your help and time.-------------------
