The ESTAR module is a finite element based program for solving electromagnetic problems. The program uses a state-of-the-art iterative solution technique that analyzes large models up to 10 times faster than standard procedures, while requiring a fraction of the disk space. 

The main capabilities of the ESTAR program are:

Magnetostatic analysis for two-dimensional and axi-symmetric problems with current sources and permanent magnets. 
Magnetostatic analysis of general three-dimensional models with permanent magnets and current sources. 
Electrostatic and current flow analyses of two- and three-dimensional models. 
Transient electromagnetic analysis for two-dimensional and axi-symmetric problems. 
AC (time harmonic) eddy current analysis for two-dimensional and axi-symmetric problems. 
Ability to use the result outputs for electro-thermal and magneto-structural coupling analyses. 
Capacitance matrix calculation for multi-conductor transmission lines. 
Nonlinear analysis: B-H material curves and/or permanent magnet demagnetization curves. 
Program's result output includes magnetic flux density, field intensity, forces, torque, inductance, capacitance matrix, input energy, stored energy and coenergy, voltage, electric field, induced eddy currents and power loss.
