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.
SMA connectors are popularly used on printed circuit boards (PCB) for testing. This model shows how to excite an SMA connector on a microwave substrate and how to terminate a grounded coplanar waveguide (GCPW) with 50 ohm using a lumped port and an air-bridge. Read More
Hydrodynamic bearings generate heat due to the viscous losses in the lubricant. As a result, the temperature of the rotor increases, causing deformation and thermal stresses in both the rotor and the bearing housing. This example shows how to model different physical phenomena involved ... Read More
This app demonstrates the following: Geometry parts and parameterized geometries Using tables for user input parameters Visualization on a 2D cross-section of a 3D geometry Improved visualization and user experience when a geometry object (the air object) is hidden. Induction heating ... Read More
This model extracts spice parameters for a silicon p-n junction diode. The spice parameters are used to create a lumped-element equivalent circuit model of a half-wave rectifier that is compared to a full device level simulation. In this example, a device model is made by connecting a 2D ... Read More
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... Read More
In this model example, you will study the creep behavior of a material under non-constant loading. You will model primary creep using a Norton–Bailey law and study the difference between the time-hardening and strain-hardening methods available in COMSOL Multiphysics. The model is taken ...

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
Electrochemical supercapacitors feature relatively higher energy densities than conventional capacitors. With several advantages, such as fast charging, long charge–discharge cycles, and broad operating temperature ranges, electrochemical supercapacitors have found wide applications in ... Read More
This example models 3D supersonic flow, including the effect of a shock, in a straight channel with a small obstacle on one of the walls. As the flow hits the obstacle, shock waves are diffracted from the obstacle and walls of the channel. The propagating shock waves form a pattern in ... Read More
This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. This model predicts the battery behavior to make comparisons of the monitored properties. They can be used to understand the ... Read More
