This tutorial model shows a virtual test setup of a conference speaker. The speaker system consists of a loudspeaker as well as three microphones. The model instigates the loudspeaker sound radiation, feedback, as well as the ability of the system to detect sound (speech) emitted from a ... En savoir plus
This is the model of the acoustics in a particulate-filter-like system. Real systems, like diesel particulate filters (DPFs), are designed to remove/filter soot (diesel particles) from the exhaust of diesel engine vehicles. The porous medium in such systems are typically structured with ... En savoir plus
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... En savoir plus
This tutorial application demonstrates the modeling of a hinge joint between two bodies in COMSOL Multiphysics. Various nodes available for joints such as Constraints, Locking, Spring, Damper, Prescribed Motion, and Friction are also demonstrated. Many real structures can be ... En savoir plus
Roller conveyors are commonly used in warehouses, manufacturing units and baggage handling applications to transport objects from one place to other by gravity, power, or manually. A typical roller conveyor consists of an array of moving rollers arranged either in a straight or curved ... En savoir plus
This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. En savoir plus
A common verification problem for geotechnical problems is a shallow stratum layer of clay. In this example a vertical load is applied on the clay strata and the static response and the collapse load are studied. The clay is modeled as an elastic-perfectly plastic material and the ...

This conceptual example shows how to handle a transient contact problem with stick-slip friction transition. A soft hollow pipe subjected to gravity is released at the top of a halfpipe. The pipe motion varies between sliding and rolling, depending on its position in the halfpipe and its ... En savoir plus
In this tutorial model, different methods for modeling brittle damage are compared in a simple model of a uniaxially loaded bar. The localization of the deformation during fracture is studied using different discretization orders and regularization methods. En savoir plus
This model example shows how to model nonlinear propagation of 1D finite-amplitude Acoustic waves in fluids using Acoustics Module of COMSOL Multiphysics. The model is based on the 2nd order Westervelt equation. The one dimensional nonlinear wave equation is solved in the time domain by ... En savoir plus
