This example simulates particles in a range of sizes that move through different levels of a cascade impactor. A cascade impactor is an inertial particle separation device consisting of multiple levels separated by collecting plates and nozzles. Particle-laden air enters from the top ... En savoir plus
The Ion Range Benchmark model simulates the passage of energetic protons through silicon with both ionization losses and nuclear scattering. The initial energy of the protons is varied using a parametric sweep from 1 keV to 100 MeV. The average path length of the protons is compared to ... En savoir plus
This tutorial series describes in two different ways how to organize a more complex geometry. En savoir plus
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. En savoir plus
When simulations are involved in the development of mobile devices, consumer electronics, hearing aids, or headsets, it is necessary to consider how the transducers interact with the rest of the system. Here, we show an analysis of the interaction between a vibration isolation mounting ... En savoir plus
Lamb-wave resonators are useful components for many radio-frequency applications. This example shows how you model an aluminum nitride Lamb wave resonator and perform eigenfrequency and frequency-response analyses to characterize the device. The tutorial uses the Electric Currents in ... En savoir plus
Lithium-ion batteries can have multiple active materials in both the positive and negative electrodes. For example, the positive electrode can have a mix of active materials. These materials can have different design properties (volume fraction, particle size), thermodynamic properties ... En savoir plus
In this example, three parallel pipelines of length 68 km and a horizontal separation distance of 10 m between them are protected against corrosion by an impressed current cathodic protection (ICCP) system using a series of anodes. Each anode is connected to all three pipelines, ... En savoir plus
Porous materials are frequently represented through periodically arranged microstructures. To compute porous media flow, the macroscale permeability and porosity is used which can be calculated from the creeping flow results through the microscale unit cell. In this application, various ... En savoir plus
Surface micromachined thin films are often subject to residual stress. This COMSOL Multiphysics example describes a thin film resonator with straight or folded cantilever beam springs. The resonance frequencies of the resonator are affected by thermal stress. Using folded springs ... En savoir plus
