Specifically magnetostatic, AC magnetic, and transient magnetic modules.
EMS is a 3D electromagnetic field simulator software suite, based on the powerful finite element method. Currently, it is the only electromagnetic Add-in to SolidWorks®, the #1 CAD package. EMS is Gold Certified by SolidWorks® and targets four main areas: electromechanical, electromagnetic, power electronics, and electromagnetic behaviour. Each of its five modules: Electrostatic, Conduction, Magnetostatic, AC-Magnetic, and Transient, has a built-in fully integrated thermal solver. EMS empowers the designer to compute electric, magnetic, mechanical, and thermal parameters including, force, torque, magnetic flux density, magnetic field, electric field, electric flux, current flow, eddy current, inductance, capacitance, resistance, flux linkage, core loss, saturation, induced voltage, force density, power loss, temperature, temperature gradient, heat flux and more.http://www.emworks.com/product/preview/1http://www.emworks.com/download/ems_show_form
