FloWorks/Cosmos thermal board analysis 3

[JordonMusser]

Basically, I am modeling a few key components on a board and doing a thermal analysis in an enclosure. I need to model the thermal resistance between the junction and the board and junction and the ambient so that I can accurately predict junction temperature (for reliability calcs)

I have theta j-a and j-c for some components. I have the component modeled and the board (simple, just a block). I was going to use J-C, multiple by surface area and use that for contact resistance between the part and the board. Then do the same with J-A for a convection coeff on the other 5 surfaces on the part.



Is this the right way to simulate this? Or a better way? Are there good "rules of thumbs" or ways to do this? thanks

I personally have not done this, but have worked with an engineer that has. From me watching him, it seems what you are doing currently seems good.
Maybe try forum "Computational Fluid Dynamics CFD"?

Cosmos it's very interesting tool but sometimes it's hard to use
