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.
Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... Read More
This tutorial model simulates a pair of straight conical bevel gears. The gears are modeled as rigid, but one of the gears is fixed while the other is hinged on a rigid bar. The rigid bar is also hinged at a point lying on the axis of the fixed gear. A transient analysis is performed to ... Read More
This is a benchmark model for rigid body dynamics. This model simulates the dynamic behavior of "Andrew’s squeezing mechanism", which is force driven and requires a very small time scale. Various angles in the mechanism are compared with the results from the reference. Read More
In this example, the Extended Barcelona Basic Model (BBMx) is used to model oedometer, uniaxial swelling, triaxial, and constrained swelling tests on bentonite clays in order to recover the hydromechanical characteristics of the soil samples. There is a good qualitative agreement ... Read More
This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells. The model takes heat transferred through both ... Read More
This model analyzes the nonlinear transfer impedance of a tapered orifice that can be part of a perforate or microperforated plate (MPP). The analysis is carried out for various degrees of tapering of the perforate and for a frequency range. A linear analysis is set up in the frequency ... 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
Example for a geometry sequence to deduce a shell model from an imported solid CAD file. The model demonstrates how to generate parameters from dimensions of a geometry and how to convert a solid CAD geometry into a shell representation using midsurface and extract Read More
This example models the flow and mass transport in the channels and the gas diffusion layer (GDL) of a polymer electrolyte fuel cell. The cathode electrode reaction is modeled as a boundary condition, where the local current density depends on the overpotential and the local oxygen ... Read More
The transmission speed of optical waveguides is superior to microwave waveguides, because optical devices have a much higher operating frequency than microwaves, enabling a far higher bandwidth. This model is an example of a single step-index waveguide made of silica glass. The inner ... Read More
