Reply To: different torques for different region sizes for my 3D machine

[Timos]

Hello,

It is possible to obtain different torque by changing the region size because of the boundary condition that is applied on the faces of the region. The default boundary condition on the region boundary in 3D is that flux is tangential. So there will be a discrepancy on the simulated flux lines. Please consider to increase the region size in a way that your torque is stabilized (not touching and bigger than your stator).

Best regards,

Timos
