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 ...

Using the Curvilinear Coordinate Interface for Heat Transfer Modeling

This model and presentation shows how to model anisotropic properties of fibers in a heat transfer simulation. Because the fibers orientation is not easy to define explicitly, the curvilinear coordinate interface is used to define the fiber orientation. The fibers have high thermal conductivity in the fiber direction and low conductivity in the perpendicular direction.

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 ...

Eigenmodes of a Two-Speaker System in a Living Room

The placement of furniture in a living room affects the acoustic characteristics of a room. This model returns the eigenfrequencies around 90 Hz and the response at any point in the living room for frequencies up to 500 Hz. It includes absorbing and damping characteristics from some of the furniture.

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.
