Problem with creating internal flow volume

Also, after having setup everything else, the number of contacts is still refusing to load on the flow region export. The number of contacts will only load if I create a conjugate heat transfer on the original battery pack that has not undergone any changed under CAD mode but then this will result in partial interfaces. So do I simply wait or is there another solution for this?

This warning pops up when I try to run the simulation when the contacts have no loaded yet:

I believe the Area average 3 resulted as I am trying to see the temperatures across the surface of all 456 battery cells but I don’t understand the bodies in the domain not being all connected through interfaces (possibly due to contacts not loading yet?).
