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 example uses the Granular Flow interface to model the formation of the grain heap and then its subsequent spreading using a cylindrical roller. The roller has a combined rotational and translational motion. The resulting powder bed is then analyzed to determine its quality based on ... 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
In this application, a solution is pumped through a catalytic bed where a solute species reacts as it gets in contact with the solid catalyst. The purpose of this example is to maximize the total reaction rate for a given total pressure difference across the bed, by finding the optimal ... Read More
This application performs parameter estimation (fitting) of the active lithiation windows of the negative and positive electrode materials of a lithium-ion battery, based on a experimental open-circuit voltage (OCV) curve measured as a function of the cell state of charge (SOC). Once a ... Read More
In this extension of the model Optical Scattering off a Gold Nanosphere, the transmission spectra due to spherical nanoparticles of gold with varying radii dispersed in glass are computed and mapped onto the CIE 1931 and sRGB colorspaces. For a description of this model, see the ... Read More
This model describes the corrosion of magnesium (Mg) alloys in physiological environments using a phase-field formulation. The approach couples Mg dissolution kinetics with ionic transport, enabling the transition from activation-controlled to diffusion-controlled regimes to be captured. ... Read More
The model used is the P2D model also called the Newman model. Parameter estimation is run using experimental data of driving cycles from healthy cells. The parameter values are determined for a confidence of 0.95 for each parameter. Parameter estimation is then run using data from ... Read More
The electrodes of a lithium-ion battery are porous and consist of an active solid electrode material, a binder, and pores filled with a liquid electrolyte. Expansion of the active material due to lithium intercalation changes the volume fraction of electrolyte-filled pores in the ... 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
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
