The dipole tonal noise generated by flow over a cylinder in free space is modeled using a two step hydrodynamic/acoustic splitting method. First, the unsteady hydrodynamic flow field is calculated using the incompressible Navier-Stokes equations. Second, the Linearized Perturbed ... En savoir plus
Find the optimal cross section areas of trusses in a structure given a prescribed set of limitations and a clear objective. The structure is made up of trusses which are elements that can only sustain axial forces. En savoir plus
This example shows how to model Lithium diffusion in a silicon electrode that swells. The model shows how swelling-induced plastic deformation can increase the maximum state of charge (SOC). En savoir plus
This application illustrates a modeling approach for deriving physically consistent simplified models in the Acoustics Module. The approach consists of converting complex sub-components to an impedance boundary condition and otherwise using simple acoustics throughout the COMSOL model. ... En savoir plus
This model uses the Ray Acoustics interface to extract statistical information about a room. Two examples of rooms are analyzed: The staircase from the One-Family House Acoustics tutorial model A long corridor The models compute the mean free path as well as the reflection frequency ...

The purpose of this model is to demonstrate pure rolling of a rigid wheel when given an initial forward velocity together with a prescribed lean about this direction. It is assumed that the the rolling motion of the wheel is not affected by contact such that all three components of the ... En savoir plus
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. En savoir plus
During manufacturing or in-service use, the geometric shape of structural components can deviate from their intended design. For example, a hole may lose its perfectly circular form, making it important to measure and control this deviation. The process of quantifying such deviations is ... En savoir plus
When computing ray intensity in 2D axisymmetric models, the wavefront associated with the propagating ray is treated as a spherical or ellipsoidal wave, instead of a cylindrical wave. This tutorial example illustrates how to set up several important features using the Ray Acoustics ... En savoir plus
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...
