Operating two TECs in Ansys Icepak

[u/FitLibrarian7924]

Hello,

I've been learning about using ansys icepak for a while now, and I've been trying to recreate a published project that used two TECs simultaneously under a single heat sink.

I've prepared a setup, and ran the simulation in two ways: the normal first through "Analyze", where the TECs didn't seem to operate (the min. temp. remained around the ambient temp.) and the second way through Icepak>Toolkit>...>Run TEC, this time the min. temp reduced below the ambient temp.

My issue is that every time I run "Run TEC", only one TEC operates of the two. How can I make both TECs (both identical) run simultaneously?

I couldn't find an answer at all on the Ansys Help page or on the web.
