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.
The miniaturization of electronics devices requires batteries with higher energy density and power. To increase the contact area between the electrodes and the solid electrolyte, 3D configurations such as the trench geometry are used. This example demonstrates how to model a solid-state ...

Manual design optimization typically requires numerous sweeps over a parameterized geometry, but it does not guarantee optimal performance under given conditions. Shape optimization removes the need for explicit parameterization and can achieve comparable or even better performance in a ... Read More
This example exemplifies how to compute the design sensitivities of your COMSOL Multiphysics® model. A more detailed description of the modeling process can be seen in the blog post "Computing Design Sensitivities in COMSOL Multiphysics". Read More
This example illustrates a linear buckling analysis conducted for a corrugated conical shell, utilizing a single sector of the geometry along with cyclic symmetry periodicity edge conditions. The results are compared to those using the full shell geometry. Read More
This model shows three methods to focalise external irradiation with a convex glass lens made of either: Semitransparent Surface with no reflection. Refractive Interface following the Fresnel's relations. Dielectric Window absorbing ultraviolet and infrared radiations. Read More
Turbulent flow, Elliptic Blending R-ε interface is used to analyze fully developed turbulent flow in a spanwise rotating channel. Due to the influence of Coriolis force on turbulence, profiles of the flow variables are skewed at moderate rotation rate. The asymmetry between cyclonic ... Read More
This example demonstrates how to set up text files to use when preprocessing models that contain hundreds of parts. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Automate Model Preprocessing with the Application Builder". Read More
This 3D model example demonstrates the use of the Lead-Acid Battery interface for modeling current distribution in full cell employing a lead-acid battery chemistry. The lead acid battery chemistry uses PbO2 as the positive porous electrode and Pb as the negative porous electrode and ... Read More
This example exemplifies how to model applications using the Events Interface where a thermostat is simulated. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Implementing a Thermostat with the Events Interface". Read More
In this model, the electrical performance of a W-band waveguide to microstrip line transition (WMLT) is investigated. A standard WR10 waveguide is used and the transition from waveguide to microstrip line is achieved by utilizing the longitudinal probe (also known as E-plane probe) ... Read More
