The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
Steel pipelines are often subjected to complex stress/strain conditions in the oil and gas industry. Additionally, pipes are subjected to significant longitudinal strain due to soil movement. For the elastoplastic stress simulation, the Solid Mechanics interface is used with the small ... Read More
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... Read More
The principle component of a quadrupole mass spectrometer is the mass filter which is used to filter ions with different charge to mass ratios. The quadrupole mass filter has been well studied over the years, Ref. 1 and the physics and optimal design are well understood. In a real ... Read More
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. Read More
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... Read More
Phase separation occurs when a binary system is quenched from its stable, homogeneous one-phase state into the two-phase region of its phase diagram. The spontaneous separation of two immiscible fluids is sometimes referred to as spinodal decomposition. Each phase tends to separate into ... Read More
Battery electrodes featuring large heterogeneities in terms of particle sizes may sometimes not be adequately described by homogenized models using one single particle size only. As an alternative to adding multiple instances of the Additional Porous Electrode material node, this ... Read More
This model reproduces the NiCd battery model and the results presented in De Vidts' and White's paper from 1995. Ref: P. De Vidts, R. E. White, “Mathematical Modeling of a Nickel-Cadmium Cell: Proton Diffusion in the Nickel Electrode”, J. Electrochem. Soc, Vol. 142, No. 5, May 1995. Read More
In this model, compute the propagating modes in the chamber of an automotive muffler. The geometry is a cross-section of the chamber in the Absorptive Muffler example. The model’s purpose is to study the shape of the propagating modes and to find their cut-off frequencies. As discussed ... Read More
This example resembles the well-known double-slit interference experiment often demonstrated in schools with water waves or sound. The model mimics the plane-wave excitation with two thin waveguides leading to slits in a screen and computes the diffraction pattern on the opposite side of ... Read More
