force density on stator ring
Hi all,
I have a small problem to calculate the force density on a stator ring of an inner rotor airgap winding. Here is the cross section:
I work on base of the machine_magstadyn_a.pro and placed a Physical Line on the inner stator diameter and added it as Region to a Domain called DomainLineForce. Then there is a new Postprocessing: { Name LineForce; Value { Term { [ (T_max[{d a}] * XYZ[]) ]; In Domain; Jacobian Vol; } } } and finally a PostOperation: Print[ LineForce, OnGrid DomainLineForce, File "LineForce.pos", LastTimeStepOnly, AppendTimeStepToFileName 1];
The result is here:
What surprises me is, that according to theory, I would expect the force vector to point to the airgap with low permeability and not to the stator yoke with high permeability.
Did I messed up the Postprocessing equation?
Thanks in advance.
