Squeeze Film Disc

This benchmark model computes the total force acting on a vibrating disc in the frequency and time domains and compares both results with expressions derived analytically. When the vibration amplitude is small enough that the system is linear the frequency and time domain results agree well with theory. Larger amplitude vibrations, which result in a non-linear response that cannot be modeled in ...

Reaction Chain

This model describes the simultaneous transport of three solutes in a chain reaction within a variably saturated flow field. Involved are advection, dispersion, sorption, biodegradation, decay, and volatilization. The parent solute decays to a daughter product, which generates another tracked daughter. Built on the flow field described in Sorbing Solute, the transport scenario described here ...

Optimization of a Tuning Fork, Modeled with LiveLink for SolidWorks

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from SolidWorks via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Simulation of a Microrobot, 2D version

In this example, one of the legs of a silicon micro robot is modeled in COMSOL Multiphysics. A technique based on polyimide V-groove joints is used to get each of the legs to move. The polyimide has a relatively high coefficient of thermal expansion, and this causes the leg to bend slightly when the polyimide is heated. In the COMSOL Multiphysics simulation, a heat transfer model is coupled ...

Mechanics of Golf Swing

How well you can strike a golf ball is not only determined by your muscle strength, but more importantly it is influenced by the mechanics of golf swing. The outcome of golf stroke is basically determined by the movement of the club head just prior to the impact with the ball. In this example, a multibody analysis of a golf swing is performed. Aim of the analysis is to maximize the club head ...

Ammonia Synthesis PFR

This example demonstrate the modeling of a plug flow reactor for the synthesis of ammonia in the Haber-Weiss process. The catalytic reactor in this process operates under non-isothermal conditions, where temperature and pressure varies substantially along the length of the reactor, in addition to the variation in composition.

Accelerated Life Testing

Fatigue testing of nonlinear materials with creep mechanism is a time consuming process. In accelerated life testing the experiment time is greatly reduced by subjecting the material to testing conditions in excess of the operating one. In the model an aggressive thermal load cycle is simulated and its effect on the fatigue life of a solder joint is examined. This example demonstrates how to ...

Reactive Muffler

This is a benchmarking model to compare the abilities of COMSOL to an analytical solution. The model examines the sound-transmission properties of an idealized reactive muffler with infinitely long inlet and outlet pipes and one expansion chamber. The infinitely long inlet and outlets are simulated through a reflection-free source at the inlet pipe and a reflection-free end of the outlet pipe, ...

Capacitance in a Microstrip

To illustrate how to calculate lumped parameters of capacitance, this model calculates such in a microstrip. The example shows the two different ways of calculating this: with a static analysis and with a time-harmonic analysis.

Pacemaker Electrode, Modeled with LiveLink for SolidWorks

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in SolidWorks by using the LiveLink interface.
