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 describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... Read More
This app demonstrates the usage of a surrogate model function for predicting the rate capability of an NMC111/graphite battery cell. The rate capability is shown in a Ragone plot. The surrogate function, a Deep Neural Network, has been fitted to a subset of the possible input data ... Read More
This tutorial example of the pasta extrusion process shows how to simulate the non-isothermal flow of dough in the metering zone of a pasta extruder accounting for the temperature dependent material properties of the hydrated semolina dough. Read More
The Schmidt-Cassegrain Telescope demonstrated in this tutorial is a classic design using an aspheric corrector lens and two spherical mirrors. The aspheric corrector is created using the 'Aspheric Even Lens 3D' part from the Ray Optics part library. Read More
RF coils are important in numerous applications ranging from wireless technology to MRI scanning equipment. This introductory tutorial model demonstrates how to find the fundamental resonance frequency of an RF coil as well as how to perform a frequency sweep to extract the coil's Q ... Read More
This tutorial model solves for an inductively coupled plasma reactor in a mixture of argon/oxygen. The model computes the fluid flow and gas heating. Important aspects and strategies for modeling electronegative discharges are discussed. Read More
The model simulates non-premixed turbulent combustion of syngas (synthesis gas) in a simple round-jet burner. Syngas is a gas mixture, primarily composed of hydrogen, carbon monoxide and carbon dioxide. The name syngas relates to its use in creating synthetic natural gas. In the model, ... Read More
This model computes the ion energy distribution function (IEDF) for a commercial capacitively coupled plasma reactor. The results show good agreement with experimental data. Read More
This model simulates vibrations in a compound gear train. Spur gears, used to model the gear train, are mounted on rigid shafts. The shafts are supported by an elastic housing at both ends. The gear mesh is assumed to be elastic with varying stiffness, which is the source of vibration. A ... Read More
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Read More
