I'm working on a combined (external and internal) natural convection analysis for a sealed electronics enclosure (including radiation). The autodesk help files indicated that one of the wetted internal surfaces of the sealed air volume needs a pressure assigned in order for the analysis to be fully defined. However, depending on what internal surface I choose, I get pretty big (10 degree C) temperature differences in the analysis. How can I choose which surface(s) to apply the internal pressure boundary condition on to get the most accurate results?

Hi,
You should be OK to skip that in CFD 2015 🙂
Feel free to share a model if it helps.
THanks,

We are running CFD 2014. Would it still make sense to skip the internal pressure boundary condition completely? Or would that leave that air volume not fully defined?
Skip it 🙂
CFD should account for it automatically.
