TEC DevicesTroubleshooting TEC Simulations for Unrealistically High Temperatures

Issue:

An analysis containing a thermoelectric cooling (TEC) device material seems to have temperatures that are unrealistically high. The resultant temperatures fluctuate wildly, and the TEC has exceeded its maximum current.

Solution:

Solution

There are two things to look for: 

1. Check the setup of the TEC device parameters within the Materials task. Verify that the limiting parameters and Cold-Temperature Surface are correctly defined. 

2. Ensure that the device is properly sunk to the surrounding case. If a TEC device is suspended in space with no conduction path to the ambient, temperatures can climb wildly and result in poor results.
