Solves the electric field distribution and current distribution when the voltage is applied to dielectric and conductive materials. Harmonic analysis is also available, which will acquire the capacitance across electrodes and capacitance matrix for multiple electrodes. A force applied on dielectric material can be solved too.

In the example below, four parallel conductive plates with potential difference are placed in the air.The capacitances across the electrodes, the electric field distribution, and the equipotential map are solved.

Solves the magnetic field distribution generated by coils and magnets. Harmonic analysis calculates the induced currents in conductor as well as the inductance and coupling coefficient. Coils, magnets, and transformers can be analyzed.

An example below is the analysis of electromotive force generated in the secondary coil when the current runs in the primary coil. The electromotive force and magnetic field vectors in the secondary coil are solved.

Solves the propagation constant, S-parameters, resonance of waveguide. Devices such as electric filters, antennas, waveguides, and resonators can be analyzed.

Below is an example of bipolar antenna. An animation can be created easily.

Solves the deformation and stress distribution generated by such factors as pressure, load, acceleration, and thermal load. Resonant analysis and harmonic analysis are also available. It is useful in various analysis scenes of stress and strength from electronic and mechanical devices to large-scale production facilities.

Below is a drop test of substrate of mobile phone. You can see the behavior immediately before and after the collision.

Below is an example of fatigue life when a thermal shock is applied to a component that is soldered to a substrate. You can calculate how many heat cycles will lead the component to breakage.

Solves the temperature distribution in a solid. Steady-state and transient analyses are available. Nonlinear analysis is also possible and its results can be used for thermal analysis. It is useful to solve the heat problems of substrates, electronic components, etc.

Below is an example of induction heating. The induced current is generated on a frying pan when the current is applied on a primary coil. You can see how Joule loss, which is created by the induced current, is transformed to heat and heats up a frying pan. In this way, induction heating coupled analysis is possible, which combines electromagnetic field analysis and thermal analysis.

Solves vibration distribution and impedance characteristics of electronic devices using piezoelectric single crystals such as quartz and piezoelectric ceramics. Piezoelectric filters, oscillators, and surface wave devices can be solved.

Below is an example of the thickness-shear vibration mode of AT-cut quartz. The frequency characteristics of electrode's impedance and the displacement vectors of thickness slip of piezoelectric materials are solved.

Solves the sound pressure distribution and directivity of speakers, microphones, and ultrasonic sensors. If coupled with piezoelectric analysis, it solves the sound waves caused by the piezoelectric vibrator for example. The sound pressure distribution and the particle speed distribution can also be obtained.

Below is an example of sound pressure propagation in the air due to the hemisphere's vibration. The sound pressure distribution in the air and potential of the surrounding piezoelectric material are simulated.
