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 model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Read More
These two apps can be run to set up a digital twin of an electric scooter battery. The Digital Twin Simulator of an Electric Scooter Battery (the "simulator" app) simulates the use of an electric scooter and generates battery current and voltage data over time. The Digital Twin ... Read More
This tutorial uses an equivalent circuit approach for modeling the performance of a lithium-ion battery, requiring no knowledge about the internal chemistry or structure of the battery. A 0D equivalent circuit battery model is defined based on a resistor connected in series with a ... Read More
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... Read More
The copper current collector on negative graphite electrodes in lithium-ion batteries have been seen to dissolve at over discharge. This can be a safety concern as the dissolution damages the current collector irreversibly and dissolved copper ions can redeposit and form dendrites. ... Read More
An aperture is often used in electroplating baths in order to improve the uniformity of the deposited metal layer. This example simulates electroplating of a printed circuit board (PCB) in 3D using a secondary current distribution. The size and aspect ratio of the aperture is optimized ... Read More
