hi guys,

i did a flow simulation to study heat dissipation for a LED in a casing. compare with fluke thermal imager, the result is not even close. So wondering do i have mistake in the setting, therefore would like to ask :

1. normally how you guys define the LED material? or which material you use to define LED?

2. for the heat source of the LED, should i choose surface or volume source for heat generation rate?

3. Out of these 2 ( LED Heat, LED Optical Power) data, should i go for LED heat or LED optical power?

Looking forward for some replies. thanks!
