Can't get this simple thermal setup to solve

[Anonymous]

Hello everyone,

In an attempt to understand the thermal behaviour of a lamp I am building, I'd like to examine the effects of a heated up LED on a wooden frame. Now I know wood is not an option when it comes to thermal simulation so I just replaced that part with PMMA for now. I just apply a convection load of 5 W to all surfaces (stagnant air) and give the LED board an applied temperature of 75 C°. This fairly simple setup always fails though. Can anyone shed some light on what's happening here? Would be greatly appreciated.

Best wishes,

Patrick

Do you have contacts defined?

Additionally...an applied temperature is almost never the correct load when simulating components at steady state. Its normally something like watts.

Yeah I had them auto-defined. But besides a better way of applying a load, that’s not what’s causing this to fail or is it?

So I just reinstalled Fusion because I couldn't even solve problems which had been verified by others. Figured my install was corrupted and after reinstalling it seems to work just fine now. Weird but guess this is solved then...
