Unable to get any variation in temperature for Joule Heating Effect?

I am working on a heater coil where the input is the current and my aim is to check the rise in temperature. I am using the SWX Flow Sim (Electronics Module) to calculate the rise in temperature based on the Joule Heating concept. But unable to get any variation in temperature and I don't know why? I will be glad if anyone can just help me with this. I have attached an image and the SWX file with the study setup of an small coil for further reference.
