Weird Stuff in Flow Simulation

Hello:

 

I ran a thermal analysis in SW Flow Simulation. It was an internal flow with solid conduction. My model included 2 TECs to pump heat out of the chamber to the ambient. I also used 2 heat sinks with fans (heat sink simulation features). Air was fluid. Everything started out at high initial temperature. Internal fluid was to be cooled down to a target temperature. Steady state analysis was Ok and the results made sense. But, when I attempted to run time-dependent analysis, the temperature exploded to really high value. I really have no clue to why this happens. I really appreciate anyone give me a few pointers to figure this out.

 

Thanks so much.

 

Jeff
