Hexagonal Grating (RF)

A plane wave is incident on a reflecting hexagonal grating. The grating cell consists of a protruding semisphere. The scattering coefficients for the different diffraction orders are calculated for a few different wavelengths.

MOSFET with Mobility Models

This model shows how to add several linked mobility models to the simple MOSFET example.

Modeling a Biconical Antenna for EMI/EMC Testing

Biconical antennas are popular for very high frequency (VHF) measurement because they support a wide frequency range. They are also useful for electromagnetic compatibility (EMC) testing where the antenna can be used as an RF source in susceptibility or immunity test. This model simulates a biconical antenna made of lightweight hexagonal frames that are preferred over solid cones for ...

Rotating Galaxy

This tutorial model shows how to add customized particle-particle interaction forces. In this example the gravitational force between 2500 stars in a galaxy is modeled. The galaxy initially rotates as a rigid body, then begins to change shape due to gravitational forces.

Maxwell-Stefan Diffusion in a Fuel Cell Unit Cell

In concentrated gases and liquids, where the concentrations of species are of the same order of magnitude, there is no obvious solvent-solute relationship. Fick’s law for diffusion accounts only for one-way solute-solvent interactions whereas the Maxwell-Stefan equations account for all interactions of species in a solution. In a system with three components, three pair-wise interactions are ...

Parameterized Concrete Beam

Reinforced concrete beams are commonly used in modern construction due to their strength and durability. By simulating such beams, engineers can ensure that the resulting structures both perform well and are safe. With simulation apps, engineers of all levels of expertise can analyze and test different designs with ease. The Parameterized Concrete Beam demo app focuses on the structural ...

Monopile with Dissolving Sacrificial Anodes

A monopile foundation is a large-diameter structural element that can be used to support structures like offshore wind turbines. This application exemplifies how the cathodic protection of a monopile decreases over time as the sacrificial anodes dissolve. The model can be used to evaluate secondary current distribution electrode kinetics on the protected steel structure by taking into account ...

Thermal Bridges in Building Construction - 3D Iron Bar Through Insulation Layer

This model studies the heat conduction in a thermal bridge made up of an iron bar and an insulation layer that separates a hot internal side from a cold external side. The heat flux between internal and external side and the maximum temperature on the external wall are compared them with published values. This example corresponds to the case 4 described in the European standard EN ISO 10211 ...

Geometric Parameter Optimization of a Tuning Fork

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Solid Edge via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Temperature Field in a Cooling Flange

A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer coefficient. The natural convection cooling is modeled using tabulated empirical transfer coefficients that are ...
