SubscriberI wonder is there a specific reason why Ansys does not provide support for Transient Two-Way Coupling? The current configuration only works for steady state simulations, and the concept solution is incorrect for transient mode.
I rised the question a year ago and I hope to receive a technical answer for it. Thank you. -

Ansys EmployeeHello Sung,
The need for a transient two way coupled analysis depends on the application.
For applications where the electrical time constants is less than the thermal time constants we dont have to couple the two physics at every instant of time. But transfer the steady state loss to thermal for temperature prediction.Â
But if you are working on applications where the temperature rise is quick ,we do have option for system coupling.Â
System coupling approach helps you in trasnfering the load between the electromagenetic and thermal solver at defined intervals of time.

SubscriberÂ
I would like to perform a simple joule heating simulation with a total duration of 3 seconds. However, the approach used by Ansys AEDT in transient two-way coupling seems to be incorrect. Ansys AEDT first solve Q3D then the obtained result will be used from the 0~3sec, after 0~3 sec is done the it do the loop to reach to the number of coupling iterations. Ideally, in a Q3D-Icepak two-way coupling scenario, the process should be as follows:
Â
- At time 0, gather data from Q3D.
- Solve Icepak for the first 0.1 seconds using the obtained data.
- Using the temperature at 0.1 seconds, solve Q3D.
- Transfer the obtained results from Q3D back to Icepak.
- Continue solving Icepak for another 0.1-second time step.
Â
By following this approach, we ensure that the coupling between Q3D and Icepak occurs in a sequential and iterative manner, with each component providing updated information to the other at appropriate time steps.
Please let me know if you require any further clarification or assistance.
Would you please to explain how do you do transient two-way coupling in ansys AEDT?
please check this postÂ

SubscriberHello Sung ki Son,Â
I would like to perform the same simulation as described in your 5 steps above. Did you find a way to do that?

SubscriberIf you are dealing with joule heating, I would recommend using Icepak's joule heating simulation. This method has been proven to be highly accurate, as we have validated it through experiments and hand calculations.
From my investigation, it seems that the two-way coupling method in AEDT is currently not defined for transient mode, as I mentioned in my previous post. You may refer to that for more information.
