The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.

Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.

Ion Range Benchmark

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 ... Read More

Comparison of Campbell Plots Using Different Rotor Interfaces

Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... Read More

Vibrating Plate in a 2D Viscous Parallel Plate Flow

This is a small 2D demonstration model that couples the Linearized Navier-Stokes, Frequency Domain, Solid Mechanics, and Turbulent Flow (k-epsilon) physics interfaces to model the vibrations of a plate located in a 2D viscous parallel plate flow. This type of model is used to model fluid ... Read More

Generating a Simulation Mesh From Scanned Data

See how to generate a mesh from scanned data via two different workflows. For both examples, the data file is imported in an Interpolation function. In the first workflow, the data is applied on a Grid dataset and a Filter dataset is used to filter out the data to represent the femur. ... Read More

Electrical Heating in a Busbar Using LiveLink™ for Excel®

Tutorial model that demonstrates how to work with COMSOL models in Excel, including loading and saving files, updating model parameters, solving, and retrieving results. Read More

Conical Antenna

Conical antennas are useful for many applications due to their broadband characteristics and relative simplicity. In this example, we study the antenna impedance and radiation pattern as functions of frequency for a monoconical antenna with a finite ground plane and a 50 ohm coaxial ... Read More

Electrostatic Discharge (ESD) Test of a PCB

This example demonstrates how an ESD event causes logic error of a microchip on a PCB board. The ESD current is based on the extended HBM (Human Body Model) and it is predefined in the Lumped Port feature. Read More

MOSFET with Mobility Models

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

Optimization of a Tesla Microvalve with Transient Flow

This example performs a topological optimization for a Tesla microvalve for an oscillating pressure drop. A Tesla microvalve inhibits backward flow using friction forces rather than moving parts, and therefore the objective is to maximize the average flow rate. The design can be ... Read More

Precipitation of Barium Sulfate

Crystallization is an important separation process in the chemical industry. It is used for the production of pharmaceuticals and industrial chemicals. It can also be used in resource recovery as a way of separating valuable materials from waste. This model solves a discretized ... Read More
