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 demonstrates the use of the Two-Phase Thin-Film Flow, Phase Field multiphysics coupling, which can be used to predict the evolution of an interface between two different, immiscible fluids in thin, narrow channels. The example here presents a free boundary lubrication ... 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 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
This model demonstrates the filtration of grains of three different sizes as they pass through two vibrating sieves of different hole sizes. Read More
Free-surface calculations in the predefined flow interfaces are currently limited to time-dependent studies when using the built-in boundary conditions. Here, a stationary formulation following Romero et al. [1] is implemented using equation contributions. The attached slides describe ... Read More
At the bottom of an oil well, the pressure and temperature can differ significantly from those at the surface. As the oil mixture flows upward and the pressure decreases, phase changes may occur. At the wellbore inlet, the mixture may already contain both liquid and gas phases. ... Read More
As an analyte band flows through a curved channel in an electroosmotically driven flow, dispersion of the band occurs due to gradients in the fluid velocity across the channel. These velocity gradients result from differences in the electric field acting at the walls within the curved ... Read More
This model presents a way to compute projected area using the Surface-to-Surface Radiation interface of the Heat Transfer Module. By computing illuminated area from a set of directions on a discretized sphere, it is possible to interpolate the projected area onto any angle of incidence. ... Read More
This model analyzes the uncertainty in focused ultrasound induced tissue heating. The material properties for the tissue mimicking material, including the uncertainty, are taken from the FDA Medical Device Development Tool: Tissue Mimicking Material (TMM) for Preclinical Acoustic ... Read More
In electrosurgery, high-power AC current from a probe is driven into tissue in order to cut and coagulate it. The current causes rapid Joule heating near the tip, and as temperatures reach 100°C, water and blood vaporize and the tissue desiccates, enabling cutting or sealing. This ... Read More
