Hello,

I am working on Ansys Thermal-Electric system to study the Peltier Cooling effect. For that I usually give two voltages as inputs (Some value of 10 V or 20 V and 0V for ground). However, it also asks me one temperature parameter. I did not get what exactly that temperature parameter is and why it is required? Because what I have seen is, the point at which I am giving the temperature, that portion of geometry always stays cool and temperature distribution within the whole geometry is dependent on where I am giving that temperature. That is why I wanted to know how Thermal-Electric system works?

Moreover, Can you please also tell me how can we study time relation with respect to distribution of temperature within the whole geometry (Temperature distribution with time)?

I will really appreciate your help.

Regards,
Mukta

You have to specify the temperature or a convection on the surface you are driving heat toward.  See Example 2.2.3 in the APDL Coupled Field Analysis Guide.  If you want to see the time variation of temperature do a transient analysis, antyp,trans, or use a Coupled Field Transient System in Workbench.
