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 considers the turbulent flow of an oil-water suspension through an orifice. The oil droplets are broken up into smaller droplets by the turbulent stresses as the suspension passes through the orifice. The aim of this model is to track the distribution of droplet sizes. The ... Read More
In this tutorial, the eigenmodes and eigenfrequencies of an air bubble in water are modeled and compared with analytical solutions. The effects of surface tension are included, allowing both the pulsating mode and the surface modes of the bubble to be modeled. Lastly, the effect of the ... Read More
Diaphragm accumulators are essential components that store energy and regulate hydraulic systems. A flexible rubber diaphragm divides the hydraulic fluid from a compressible inert gas, typically nitrogen. These accumulators perform multiple tasks, such as temporarily storing hydraulic ... Read More
Atmospheric corrosion occurs when metallic structures are exposed to humid air forming a thin electrolyte film in the range of up to a few hundred micrometers. The model presented here accounts for charge transport as well mass transport involving 10 species and 6 homogeneous ... Read More
The use of Aluminum (Al) isolator is a commonly employed mitigation strategy for galvanic corrosion between magnesium alloy (Mg) and mild steel (MS). The present model demonstrates the effect of Al isolator thickness on galvanic corrosion severity using a parametric study. The electrode ... Read More
This example shows how to set up a model of furrow irrigation in a nonuniform soil column. It employs the Unsaturated Dual Permeability feature, which links two Richards' Equations through a fluid transfer function. This scenario can be regarded as a benchmark problem for dual ... Read More
Classical MHD benchmark problem was solved analytically by J. Hartmann. He considered laminar incompressible flow between two planes (in planar duct) in transversal imposed magnetic field under next assumptions: * fully developed flow (far from inlet) * fluid properties are constant * ... Read More
This model illustrates the refraction of light while passing through an optical prism using s– and p–polarized incident Gaussian beams. The prism boundaries are coated with anti–reflection coatings. It also calculates the reflectance and transmittance to analyze the performance of anti ... Read More
In this tutorial model, a six-step thrust bearing is analyzed. A step thrust bearing consists of a stepped bearing surface on which the end of the shaft rotates. The entire assembly is submerged in a lubricant. The shaft collar is assumed to rotate without any axial motion in the ... Read More
An acoustic point source emits a pressure wave in water that travels toward a piece of glass. Cracks are formed and propagate due to high tensile stresses developed in the glass. A fully coupled acoustic-structure interaction problem including phase field damage in solids is solved in ... Read More
