Cloaking of a Cylindrical Scatterer with Graphene (RF)
In this model, we introduce a cloaking method using an electrically tuned monolayer of graphene. We will show that when a cylindrical dielectric scatterer is covered in graphene, the scattering cross section is greatly reduced at the designated frequency, making it electromagnetically ... Read More
Shell Conduction
This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution. Read More
Switched Reluctance Motor
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact so as to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and the rotor being ... Read More
Parasitic Reactions in an Electrochemical Capacitor
This model illustrates the effect of oxygen and hydrogen formation and recombination on the performance and self-discharge of an electrochemical capacitor with a water-based electrolyte. A load cycle consisting of mixed constant current pulses and rest periods at an open circuit is ... Read More
Petzval Lens Optimization
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
Enhanced Coating for a Microelectromechanical Mirror
This example demonstrates how to optimize the thickness of a microelectromechanical (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 mirror. Read More
Sonic Crystal
Phononic and sonic crystals have generated rising scientific interest for very diverse technological applications. These crystals are made of periodic distributions of scatterers embedded in a matrix. Under certain conditions, acoustic band gaps can form. These are spectral bands where ... Read More
Opto-Acoustophoretic Effect in an Acoustofluidic Trap
Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ... Read More
Uncertainty Quantification of a Bracket — Fillet Version
This example demonstrates how to use the Uncertainty Quantification Module by running a series of uncertainty quantification studies for a steel bracket. This type of bracket can be used to install an actuator that is mounted on a pin placed between the two holes in the bracket arms. ... Read More
Car Cabin Acoustics using Hybrid FEM-Ray Source Coupling
This tutorial model shows how to model car cabin acoustics using a hybrid FEM-ray approach. The particular example is that of a tweeter located in the dashboard of the car near the windscreen. A FEM based sub-model of the speaker and its immediate surroundings is used to compute a ... Read More
