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 simulates the dynamics of the shock absorber used in a landing gear mechanism of an aircraft. It analyses the stresses, as well as the heat generated in the landing gear components due to the energy dissipated in the shock absorber. A prismatic joint, with spring and damper, ... Read More
The example shows a 1D steady-state thermal analysis including radiation to a prescribed ambient temperature. The temperature field from the solution of this benchmark model is compared with a NAFEMS benchmark solution. Read More
Uncertainty quantification is used to study the effect of manufacturing variation on the performance of a 2D solidly mounted resonator (2D SMR). This tutorial shows how the resonant frequency is affected by thickness variations of the piezoelectric layer and the Bragg reflector layers. ... Read More
This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D Inventor® geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL Multiphysics ... Read More
This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are ... Read More
Failure of reinforced concrete structures involves advanced material behavior and interaction between materials. This example demonstrates how to model various stages of the failure of a reinforced concrete beam. The material model includes a coupled damage-plasticity model for the ... Read More
This is a model of an adapter for microwave propagation in the transition between a rectangular and an elliptical waveguide. Such waveguide adapters are designed to keep energy losses due to reflections at a minimum for the operating frequencies. To investigate the characteristics of the ... Read More
In small PEM fuel cell systems (in the sub-100 W range) no active devices for cooling or air transport are normally used. This is due to the desire to minimize parasitic power losses from pumps and fans, and to reduce the system complexity, size, and cost. The reactants at the cathode ... Read More
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... Read More
This model illustrates the dynamics of a car door assembly during a slam event. The system consists of a car body, a door, and rubber seals. Contact pairs are defined between the car body, rubber seals, and the door. The rubber seal is modeled using a hyperelastic material model. A ... Read More
