You can write those components with dissipated power defined into the master library(Menu Libary->Work Library, move components in the work library into the master library) and update the current work libary from the master library (Menu Libary->Work Library, Updating from Master...) next time. Another way is that you may create a CSV power file and import it. There is no way to recall environment setting.
Thanks. How much of a 'master' is the master library? I'm wondering because I have parts that may dissipate 4W on this PCB and 5W on another PCB. Is the master for each PCB or for all PCBs?
Do you have an example of a CSV power file, or know where I can find the required contents?
If a component's dissipation varies on different cases, you have to use power scaling to adjust it. Power dissipation file is simple and an easy way to your requirement, the format is like this:
If you have components with 4-5w dissipation, I strongly suggest use Flo.pcb instead of Hyperlynx thermal.
