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 is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the ... Read More
An AC contactor is a particular type of magnetic switch device, which is activated by a primary coil fed by an alternating current. Unlike DC switches, such devices can suffer from a tendency to reopen when the AC current crosses zero. The addition of a shading coil that supports ... Read More
Dialysis is a widely used chemical species separation method. One such example is hemodialysis, which acts as artificial kidneys for people with renal failure. In dialysis, only specific components are allowed to diffuse through the membrane, based on differences in molecular size and ... Read More
It is possible to generate harmonics that are multiples of the frequency of laser light by using nonlinear optical materials. This model demonstrates second harmonic generation using transient wave simulation and nonlinear material properties. A YAG (lambda=1.06 micron) laser beam is ... Read More
This tutorial example shows how to perform a random vibration analysis of a structure using power spectral density (PSD). The computations are based on the modal reduced order model (ROM). Read More
Hydrodynamic bearings generate heat due to the viscous losses in the lubricant. As a result, the temperature of the rotor increases causing deformation and thermal stresses in both the rotor and the bearing housing. This example shows how to model different physical phenomena that are ... Read More
This model demonstrates the inflation of a rubber balloon with four different hyperelastic material models. The results are compared with the analytical solution for a thin-walled, spherical vessel. Controlling the inflation of hyperelastic balloons is important in clinical ... Read More
This model simulates Gaussian to Laguerre Gaussian beam shaping with the Beam Envelopes interface, the unidirectional wave formulation. The input beam is a focusing Gaussian beam with a topological spiral phase. It is known that this phase mask converts a Gaussian beam to a donut ... Read More
This example demonstrates how an ESD event causes logic error of a microchip on a PCB board. The ESD current is based on the extended HBM (Human Body Model) and it is predefined in the Lumped Port feature. Read More
This example solves the heat transfer in an isothermal box aimed at transporting refrigerated articles such as medical materials for 24 hours. In this case, the box has to keep the contents cold for a long period of time while respecting storage temperature restrictions between 2°C and 8 ... Read More
