Hexagonal Plasmonic Color Filter
This model demonstrates how to perform simulations of an absorbing bandstop color filter, based on a hexagonal array of holes in a thin aluminum layer. The structure is hexagonally periodic but this example also shows how to set the model up as rectangularly periodic. Mehr lesen
Thermal Actuator Surrogate Model Application
The Thermal Actuator Surrogate Model application demonstrates how to accelerate computation for multiphysics analysis using a surrogate model. A surrogate model is a simpler, usually computationally cheaper model, which is used to approximate the behavior of a more complex, and often ... Mehr lesen
Electrostrictive Disc
This tutorial shows how you can use the Electromechanics interface in COMSOL's MEMS Module to model Electrostriction. Electrostrictive materials (e.g. PMN-PT) exhibit nonlinear strain as a function of electric field. This 2D axisymmetry model uses a parametric sweep of voltage to ... Mehr lesen
Topology Optimization and Verification of an Acoustic Mode in a 2D Room
This tutorial introduces the use of topology optimization in acoustics. The goal of the optimization is to find the optimal material distribution (solid or air) in a given design domain, here the ceiling of a 2D room, that minimizes the average sound pressure level in an objective ... Mehr lesen
Thin Low Permittivity Gap Comparison
The thin low permittivity gap boundary condition is meant to approximate a thin layer of material with low relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the thin low permittivity gap ... Mehr lesen
Pratt Truss Bridge
This example is inspired by a classic bridge type called a Pratt truss bridge. You can identify a Pratt truss by its diagonal members, which (except for the outermost ones) all slant down in span-wise direction towards the bridge’s center. All the diagonal members are subject to tension ... Mehr lesen
Acoustics of a Particulate-Filter-Like System
This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... Mehr lesen
Dipole Antenna with a Quarter-Wave Coaxial Balun
An antenna balun blocks undesirable currents on the outside of a cable. A quarter-wave coaxial balun (1:1) is one of the easiest designs: it works as a transformer and makes the input impedance from the inner conductor to the outer conductor infinite. This model simulates an antenna ... Mehr lesen
Neutralization of Chlorine in a Scrubber
This example studies the kinetics of the neutralization of chlorine gas in water solution. The model assumes that the fluid volume is perfectly mixed and constant. This means that the chlorine has dissolved to an almost saturated state (1·10-2 mol/m3) and that the hydroxide has also ... Mehr lesen
Pyroelectric Detector
This 2D axisymmetric model demonstrates the operation of a pyroelectric detector found in instruments for measuring laser energy. A disk of lithium niobate (LiNbO3) is sandwiched between two electrodes and connected to an external circuit. The disk is mounted on a ring-shaped ... Mehr lesen
