Use the Arkkio Torque Calculation node to define globally available torque variables for the selected domains, which is the air gap. Compared with the
Force Calculation feature, the
Arkkio Torque Calculation requires a much coarser mesh for the same accuracy. For a theoretical discussion, see the section
Computing Forces and Torques.
Enter a Torque name, which is then appended to global variables. This feature also gives access to the azimuthal and radial force density and magnetic flux density. The computed torque is made available as a global scalar variable with name
<name>.Tark_<torque name>, where
<name> is the
Name of the physics interface.
The Arkkio Torque Calculation node has to be used together with
Continuity,
Sector Symmetry or
Arkkio Extra Circular Boundaries features. The
Arkkio parameters and
Number of sectors default to be automatically retrieved in most cases. Otherwise,
User defined options are available.
