Aguilar López Ingeniería Synchronous Machines Finite Element Method Standstill Frequency Response Test This paper uses different/state-of-the-art finite-elementtechniques to effectively obtain the standstill frequencyresponse of synchronous machines.

This workuses Lagrange multipliers to create two different finiteelementmeshes that are joined at the air gap region, allowingthe existence of element nodes in other element edges andfacilitates the simulation of the rotor body movement.
