I try to simulation of 12 cells 32650 LiFePO4 battery. The picture below is configuration of my battery pack.December 22, 2021 at 7:17 pmKonstantine KourbatskiAnsys EmployeeHello which version are you using? In the current release 2021R2 the number of allowed passive zones is set to 10. Have you tried doing what the code instructs and increase the number of passive zones zones, which are tabs and bushbars.

(rpsetvar 'battery/max-n-zone-per-entity 5)
Before doing so, you can check what this rpvar is set for by:
January 14, 2022 at 10:08 pmmehmetsaiddSubscriberHello everyone, I'm trying to model multiple batteries with the msmd module, but I couldn't succeed. Can anyone help me, can I leave an e-mail for communication? If I send a sample of my work, can you tell me my mistake?
January 18, 2022 at 11:29 amPunnathorn14099SubscriberTo Keaton, I have another problem when I simulate 1 cell of 18650 with air cooling. The problem is negative and positive tab don't show up in electric contact in MSMD battery module as the picture below. Cause of this problem is the air that I assign in the battery box. But I still don't know how to fix this problem. I have tried to suppressed the air volume and n p tab show up but it not what I want it to be.
January 18, 2022 at 2:46 pmKonstantine KourbatskiAnsys EmployeeThere are quite a few resources out there on modeling batteries. A web search for "ansys fluent msmd? yields a number of videos outlining the model set up which may be required steps. Also, if you haven't done so already, absolutely review relevant sections of the User guide, i. e. Chapter 27: Modeling Batteries:
There are two tutorials on the ansyshelp site on battery modeling: 1) Simulating a Single Battery Cell Using the MSMD Battery Model, and 2) Simulating a 1P3S Battery Pack Using the Battery Model
Following those and then adapting your specific set up could be of help
