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.
Interfacial failure or delamination in a composite material can be simulated with a cohesive zone model (CZM). A key ingredient of a cohesive zone model is a traction-separation law that describes the softening in the cohesive zone near the delamination tip. This example shows the ... Read More
In a lithium metal battery, lithium metal is deposited during charging on the negative electrode. Mass transport and ohmic effects in the electrolyte cause small protrusions on the metal surface to be subjected to accelerated growth during charging. In worst case scenarios, this leads to ...

This tutorial demonstrates how to integrate multiple Lumped Battery models into the Electrical Circuit interface. Two batteries are connected in series. Each battery is protected by a shunt resistances that is activated if the battery state-of-charge reaches below a certain threshold ... Read More
Recent advances in the fabrication of microfluidic systems require handling of live cells and other micro particles as well as mixing. All this can, for example, be achieved using acoustic radiation forces and the viscous drag from the streaming flow. Streaming: Due to the nonlinear ... Read More
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 ... Read More
This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SOLIDWORKS® via the LiveLink™ interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz. Read More
This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between the Inventor® software and the COMSOL Multiphysics® software, how to modify the geometry from COMSOL Multiphysics®, and how to run a geometric parametric ... Read More
When a temperature gradient in a gas exists, suspended particles will tend to move from regions of high temperature to low. The force which produces this effect is called the thermophoretic force. Gas molecules colliding with a particle from the hot side have a higher velocity than the ... Read More
In this example, triaxial and oedometer tests are simulated using the Hardening Soil material model. Both tests exhibit a hyperbolic stress–strain relationship. For the triaxial test, it is confirmed that the axial stress approaches the analytical failure stress asymptotically. In the ... Read More
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
