This model shows how shape optimization can be used to design an acoustic demultiplexer. A demultiplexer is a data distributing device, in this case it will distribute acoustic energy. The geometry consists of a circular domain with one input port and two output ports. The domain has the ... Read More
This model computes the temperature distribution in a battery pack that is in use at a specified power. The current is controlled in Simulink® to ensure constant power during usage. Read More
This example shows how to perform parameter optimization on a lens system. The optimization is motivated by the replacement of one of the glasses in a prior optical prescription with a new glass having slightly different optical dispersion coefficients. The control parameters are the ... Read More
Hydrodynamic bearings generate heat due to the viscous losses in the lubricant. As a result, the temperature of the rotor increases causing deformation and thermal stresses in both the rotor and the bearing housing. This example shows how to model different physical phenomena that are ... Read More
Vibration and noise in washing machines, due to the non-uniform distribution of clothes in the barrel, is a common problem worth studying and optimizing for. This model simulates a multibody dynamics model of a horizontal-axis portable washing machine. An eigenfrequency analysis is ... Read More
This is a benchmark model involving stick-slip friction of a ring rolling inside another ring. The displacement of the inner ring is computed and compared to the analytical result. This model also shows how to tackle friction dominated contact problem. Read More
A helical antenna has two major modes. One is normal mode and the other is axial mode. When the helical antenna is operating at the normal mode, its far-field radiation pattern is similar to the torus shaped pattern of a classic dipole antenna. At the axial mode, the helical antenna is ... Read More
The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... Read More
In a polymerization reactor for polyester manufacturing, the mixing in the reactor is achieved by impinging turbulent jets of reactants onto each other. The turbulence affects the reaction kinetics and quality of the polymer linkage. Turbulent flows involving rapid reaction kinetics are ... Read More
This model shows how to add several linked mobility models to the simple MOSFET example. Read More
