Hello, I want to study voltage distribution along the battery grid by applying constant current. I use electromagnetic field in Ansys Discovery AIM and chose the pure electric option. When I define current on a specific face it doesn't allow me to define voltage for that face or any other face in contact with it.
It says voltage shares one or more geometric entities with current which is not allowed by the solver, define a new location for one of these loads.
What should I do to not getting this error?

many thanks,

Farnaz

Hello farnazhd66

If you look at the Physics setup options, it can be seen that you can specify either current or voltage. See below snapshot. You can define current at one terminal and voltage at another terminal.

 

I would recommend you to go through the Electromagnetics simulation examples posted at below links to get an idea on the physics setup:

Hi Naresh,

many thanks for your quick reply and all the useful information. That's right I didn't know that, but my model is in a way that I have to define current and voltage on the same face. So it means that it is not possible to be solved by Discovery AIM?

Hi farnazhd66

Yes, you are correct.
