Results

Radial and Tangential airgap flux comparison (FEMM vs Subdomain)
Radial and Tangential airgap flux comparison (FEMM vs Subdomain)

One can see that the subdomain model correctly captures all the Maxwell stress harmonics in demagnetized case in 1 sec of calculation, which is much faster compared to finite element analysis on such an asymmetrical problem.
