In acoustofluidics, acoustics is used to manipulate particles and fluids in microfluidic devices. This model demonstrates the phenomena of the inhomogeneous acoustic body force and how it can move a fluid with an inhomogeneous density due to a solute. The model is of a 2D cross section ...

Opto-acoustophoresis is a term used to describe the interplay between acoustics and optical fields. In most cases (including this) the optical field is heating up the material and therefore affecting the acoustic field. In this example of an acoustic trap a set of particle are trapped ... Read More
This model analyzes the scattering of a plane propagating modulated Gaussian pulse off a submarine hull. The scattered field and the spatial response are also determined. The model uses the Pressure Acoustics, Time Explicit interface to model this large acoustic model in the time domain. ... Read More
For models with acoustic-structure couplings it is necessary to calculate the left eigenvectors to use the Frequency Domain, Modal solver. The model shows the necessary changes to the default settings of the eigenfrequency solver. Read More
In applications where pressure waves and elastic waves propagate in porous materials filled with air both thermal and viscous losses are important. This is typically the case in insulation materials for room acoustics or lining materials in car cabins. Another example is porous materials ... Read More
This model demonstrates the motion of a bicycle with a hands-free rider when given an initial forward velocity and perturbed with a lean about the forward axis. This is implemented through the Multibody Dynamics module in COMSOL. The wheels of the bicycle have been modelled assuming ... Read More
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 ... Read More
This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... Read More
A detailed description of these models can be found in our blog post “How Should I Evaluate Singular Stress Fields?”. The models are: notchedStrip.mph – Model for the initial studies of the stress field properties. singularityPower.mph – Small model solving the transcendental equation ... Read More
In microfluidic devices, it is a challenge to mix different fluids. One method is to use acoustic streaming to create a flow which enhances the mixing of two fluids. In this model, the vibrations of PDMS structures in a channel induces fast acoustic streaming used for mixing a diluted ... Read More
