In this model a plane wave with circular polarization is reflected off an interface between air and glass. The model demonstrates three different ways of defining this problem. The first part shows how to define user-defined port mode fields. The second part uses the predefined circular ... En savoir plus
This example demonstrates how to optimize the thickness of a microelectromechanical systems (MEMS) mirror coating material for maximum reflectivity. To reduce the simulation time, a Layered Impedance Boundary Condition is used to model the thin coating material on top of the metallic ... En savoir plus
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... En savoir plus
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. En savoir plus
A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and ... En savoir plus
A tweeter is a high frequency driver used in loudspeaker systems. An ideal tweeter will produce a constant sound pressure level at a given distance in front of the driver independently of frequency, that is, a flat response. Ideally the tweeter will also, to a certain degree, maintain ... En savoir plus
Portal Cranes are common when handling heavy loads. In this example, the Beam interface is used to compute the stresses in a portal crane designed for lifting 15 tons. Three load cases are considered: self weight, payload, and thermal expansion on a hot summer day. An internal hinge ... En savoir plus
The Superlattice Band Gap Tool model helps the design of periodic structures made of two alternating semiconductor materials (superlattices). The model uses the effective mass Schrödinger equation to estimate the electron and hole ground state energy levels in a given superlattice ... En savoir plus
See how to perform a vibration analysis of the crankshaft of a 3-cylinder reciprocating engine in this tutorial model. Due to the eccentricity of the crank-pin and balance masses on the crankshaft, it undergoes self-excited vibration under rotation. The crankshaft is modeled using solid ... En savoir plus
Patch antennas are becoming more common in wireless equipment, like wireless LAN access points, cellular phones, and GPS handheld devices. The antennas are small in size and can be manufactured with simple and cost-effective techniques. Due to the complicated relationship between the ... En savoir plus
