Hello together,

i just spend a lot of time to model a battery in steady-state thermal-electric module on Ansys Mechanical and validated my model with experimental data.

Now i want to do a transient simulation where my current is changing. As joule heating plays a major role in my thermal behaviour, how can i do a transient simulation including the joule heating? Coupling my models? Import the Joule heat as heat generation, depending on my current?

I am a beginner to mechanical and have almost no experience in using APDL.

I hope someone can help me out! Thanks already!

Hi

The easiest is to run your current model (steady-state thermal-electric), and just use an apdl command snippet to change/convert it (steady-state thermal-electric) to a transient analysis.

Below is a discussion that gives the commands on how to do that (run transient).

All the best
Erik

Greetings!

 

I am interested on doing something similar. Where I can find this discussion?

 

Thanks,

Thank you !
Thats exactly what i was looking for!

Hi

We should use the native system now called coupled field transient with thermal and electric (conduction) physics. 

 

See here for more info:

Coupled Field Analysis Types (ansys.com)

Or search the online Ansys help for coupled field analysis types.

Thank you

Erik
