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.
Voltammetry at a Microdisk Electrode
Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and ... Read More
Orange Battery
This tutorial example models the currents and the concentration of dissolved metal ions in a battery (corrosion cell) made from an orange and two metal nails. This type of battery is commonly used in chemistry lessons. Instead of an orange, lemons or potatoes can also be used. Read More
Diffuse Double Layer
At the electrode-electrolyte interface, there is a thin layer of space charge in a diffuse double layer. This may be of interest when modeling devices such as electrochemical capacitors and nanoelectrodes. This tutorial example shows how to couple the Nernst-Planck equations to the ... Read More
