Issue with boundary conditions in Flux 2d thermal steady state analysis

I am simulating a 3 phase PM Outrunner motor (52 poles, 48 slots). I am trying thermal simualtions in flux, after all the setup as mentioned in examples and tutorials, this is the error i get upon physics check:

Also, I tried changing geometric symetry to even cyclic (which is incorrect as per no of slot and poles) but even then it results in following error:

Kindly help in resolving this issue.
