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.
This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... Read More
This example applies the Electrophoretic Transport and Laminar Flow interfaces to model isoelectric separation in a free-flow electrophoresis device. A stream containing six different ionic species is shown to be divided into pure component streams by means of migrative transport in an ... Read More
This model shows how to combine different types of material nonlinearity, such as creep and elastoplasticity. In this specific example you will perform a stress and nonlinear strain analysis on a thick cylinder under a nonproportional loading: an initial temperature increase followed by ... Read More
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... Read More
For slender structures, buckling is a catastrophic instability if the service load is above the critical limit. For such structures, it can be important to study the behavior of the structure beyond the critical buckling load, which is known as postbuckling analysis. Tracing the ... Read More
In signal integrity (SI) applications, time-domain reflectometry (TDR) is a useful technique for analyzing the discontinuity in a signal path by observing the reflected signal strength. The reflected signal distorts the input pulse mainly by impedance mismatch if there is no external ... Read More
This tutorial shows how to model a miniaturized magnetostrictive antenna developed for use inside living cells. The stress in the antenna, the magnetic flux density, the current density, and the displacement of the tip of the device are investigated at the resonance frequency. Read More
This tutorial investigates the acoustic properties of a porous layer made of glass wool. The porous material has transverse isotropic properties and is modeled with the full anisotropic poroelastic material model. Read More
This app demonstrates the following: Parameterized geometries Visualizing material appearance, color, and texture Multiple plots in the same window to visualize the results Options to visualize the results with different views using check boxes Microstrip patch antenna arrays are ... Read More
The heat exchanger in this tutorial model contains a dynamic wall with an oscillating wave shape. The deformation induces mixing in the fluid and reduces the formation of thermal boundary layers. Hence, it increases heat transfer between the walls and the fluid. In addition, the wave ... Read More
