Hi all,
This is my first post here and I hope I started this thread in the right spot.
I wanted to get some advice on how to expand my skill set in thermal analysis. I currently work for an avionics company and have exposure to thermals in electronic packaging for our aircraft computing.
We use 6SigmaET as our thermal analysis software, I wanted to be able build on that and for component and pcb level analysis at home.
Is there a software that is almost comparable that’s not crazy expensive?
The end goal is to start my own company for thermal and structural in the future, I love the company that I’m at but they’re not making the best decisions and I just want something to fall back on in between jobs.

Edit:
I want to clarify, I will not be using anything related to my company, I am trying to find an affordable thermal software and learn at home with using examples I find online.
