Torque calculation with conforming and nonconforming movement interface

This work analyzes the use of conforming and nonconforming movement techniques for torque calculation with high-order hierarchic interpolation in electrical machines thin air gaps. For the nonconforming movement formulation, the Lagrange multipliers are used. The moving band is used for the conforming case. The behavior of torque results as a function of interpolation order and air-gap thickness is discussed. In order to compare formulations, results for two thin air-gap machines are shown
