Equation-Based Modeling in COMSOL Multiphysics

Partial differential equations (PDEs) constitute the mathematical foundation for describing the laws of nature. This presentation provides an introduction to customizing your simulations by developing models directly with PDEs. Learn how to add ordinary differential equations (ODEs) and algebraic equations to your model. Equation-based modeling is a powerful method eliminating the need for ...

Benchmark Electromagnetic Simulation of a Coil Using Infinite Elements

Many environments where electromagnetic phenomena are modeled are unbounded or open, meaning that the fields should extend towards infinity. The easiest approach to model such is to use infinite elements. COMSOL Multiphysics' implementation of these maps the model coordinates from the local, finite-sized domain to a stretched domain. The inner boundary of this stretched domain coincides with ...

Sedan Interior Acoustics

This is a model of the acoustics inside a sedan, that is inside a typical hard-top family car. The model sets up sources at loudspeaker locations as well as impedance conditions to model soft absorbing surfaces (seats and carpet). The model results in plots of the pressure, sound pressure level, and intensity inside the car. The frequency response at given points inside the cabin are also ...

The Magnus Effect

The Magnus effect explains the curl that soccer players can give the ball, resulting in the enjoyable goals that we can see in every World Cup™. This model looks at the Magnus effect in the laminar and turbulent flow regimes for transient and stationary flows. It also discusses the simulation results and relates them to experimental measurements on soccer balls found in the literature.

One-Family House Acoustics

This model shows an application of the Acoustic Diffusion Equation physics interface. The acoustics in a two story one-family house consisting of 10 rooms is analyzed. The steady state sound pressure level (acoustic energy density) distribution is analyzed for a sound source located in the main living room. The reverberation time T60 of the different coupled rooms is then studied using the ...

Inductive Heating of a Steel Billet

A squared billet made of steel is introduced into a coil operating at low frequency. The process is used in order to make the temperature in a section of the billet homogeneous, since it loses energy faster through the edges than through the lateral boundaries. It is shown here that heating at such a low frequency is not efficient for overheating the edges, although is is very efficient for ...

Shift into gear

This model demonstrates the ability to simulate Multibody Dynamics in COMSOL. It comprises a multilink mechanism that is used in an antique automobile as a gearshift lever. It was created out of curiosity to find out how large forces are on the individual components. The model uses flexible parts, i.e. the Structural Mechanics Module was used along with the Multibody Dynamics Module.
