Thermal soakback from electrical heating

PaulFlynn

Trying to calculate the thermal soak back from electric heating of a conductor. I can run the DC current and get internal heat generation and copy the W/m3 to Thermal Transient and calculate heating vs time. Now I want to use the temperatures as a starting BC without W/m3 and calculate the soak back vs time. I copy the temperature from the transient with current and unselect the W/m3, but the nodes temperature are enforced for the whole soak back period so temperatures stay constant.

Hello PaulFlynn

I think I see your problem. I faced it when I did the whole sequence.
When transferring temperatures from solution to a Thermal transient study , the temperatures go to a "New Node Temperature BC" and it doesn't have the option "within an interval" as the "New temperature BC" has.
The solution is to transfer the temperatures from solution to the “Initial Condition folder” and not to the “Loads and constrains” folder as you did with the power density. See picture.
