The solver for electromagnetic waves analysis is called "Hertz". It solves various electromagnetic field problems for filters, antennas, waveguides, resonators, etc. Various characteristics such as propagation constants, S-parameters, etc can be acquired as well. The figure below shows the TE01-mode electric field distribution in a cylindrical dielectric resonator.
The solver for magnetic field analysis is called "Gauss". It calculates the magnetic field distribution of magnets, coils and transformers. The current induced in the conductor can be solved by harmonic analysis. The coupling coefficients and inductances can be acquired as well. The figure below shows the eddy current induced on a conductive shell when the alternating magnetic field is applied.
Luvens solves mainly distributed magnetic field or torque of rotating machinery in the transient analysis.
The figure below shows Transient Analysis for Motor
The solver for electric field analysis is called "Coulomb". It calculates the electric field distribution when a voltage is applied on conductors or dielectric materials. Static and harmonic analyses can be performed. The capacitances and the electrostatic forces across the electrodes can be acquired as well. The figure below shows the current density vectors in a U-shaped conductor when AC voltage is applied.
The solver for mechanical stress analysis is called "Galileo". It calculates the stress distribution and the deformation under pressure, mechanical load, acceleration and thermal load. Harmonic and resonant analyses can be performed as well as static analysis. The figure below shows the resonance of a tuning fork.

The solver for thermal analysis is called "Watt". It calculates the temperature distribution in and on solid bodies. Steady-state and transient analyses can be performed. Nonlinear materials can be handled. Thermal stress can be calculated from the results. The figure below shows the transient analysis of heat conduction when a heating element is placed on a substrate. You can see how the temperature distribution stabilizes steadily.
The solver for piezoelectronic analysis is called "Rayleigh". It solves various piezoelectric problems for crystals, ceramics, SAW devices etc. The acoustic impedance can be acquired as well as the vibration distribution. The figure below shows one of the vibration modes of a Langevin vibrator.
The solver for acoustic analysis is called "Mach". It calculates the sound pressure and the directivity of sounding devices such as loudspeakers. Combined with "Rayleigh", it can solve the acoustic waves generated by a piezoelectric device. The figure below shows the interference of acoustic waves coming from two sources.
