The model analyses the mode propagation within a nano slot waveguide. In a slot waveguide configuration, two high refractive index slabs (~3.48) are placed adjacent to the low refractive index slot (~1.44). Mode analysis was performed on a 2D cross section of a slot waveguide for an ... En savoir plus
Thermoelectric elements are often used to cool or heat electronic components to a desired temperature. In such simulations, you are typically not interested in the behavior of the thermoelectric element itself but want to use its performance characteristics to model the overall response ...

When a valve is closed rapidly in a pipe network it gives rise to a hydraulic transient known as a water hammer. The propagation of these hydraulic transients can in extreme cases cause failures of pipe systems caused by overpressures. This is a model of a simple verification pipe system ... En savoir plus
A 3D model of an acoustic trap in a glass capillary actuated by a piezoelectric transducer. The system is actuated by an oscillating electric potential across the piezoelectric transducer inducing mechanical vibrations in the solid and an acoustic pressure field in the fluid. The heat ...

When a conductive solid material moves through a static magnetic field, an eddy current is induced. The current that flows through the conductor, which is itself moving through the magnetic field, induces a Lorentz force back on the solid. Therefore, a conductive solid that is vibrating ...

The dynamic response of a human body in any vibration environment can be predicted using this biomechanical model. In the automobile industry for instance, this model can be used in ride quality simulation and designing vibration isolators such as seats. In this example, a ... En savoir plus
This example models heat transfer in a thin rectangular metal plate. Because the plate’s thickness is only 1/100 of its length and width, you can simulate the process using a 2D approximation. The plate has a fixed temperature at one end and is isolated at the other. A surrounding liquid ... En savoir plus
This model extracts spice parameters for a silicon p-n junction diode. The spice parameters are used to create a lumped-element equivalent circuit model of a half-wave rectifier that is compared to a full device level simulation. In this example, a device model is made by connecting a 2D ... En savoir plus
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... En savoir plus
This example simulates the insertion of a snap hook in its groove. Fasteners like this are common in the automotive industry, for example, in the control panel of a car. In this case it is important to know the force that must be applied in order to place the hook in the slot and also ... En savoir plus
