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.
Interfacial failure by delamination or debonding can be simulated with a Cohesive Zone Model (CZM). This example shows the implementation of a CZM with a bilinear traction-separation law. It is used to predict the mixed-mode softening onset and delamination propagation in a composite ... Read More
In this example of a peristaltic pump, rollers squeeze a flexible tube and the compression drives a fluid through the tube. The model demonstrates how to use the Fluid-Structure Interaction interface. The main advantage of the peristaltic pump is that no seals, valves or other internal ... Read More
A strong permanent magnet is placed close to a clamped thin plate made of iron. The magnetic force causes the plate to be deflected. This example studies the plate's elastic deformation and stress. The deformation of the plate has an influence on the distribution of the magnetic field. ... Read More
Solid-state batteries (SSB) are a promising technology that could suffer from internal mechanical stresses due to the growth and shrinkage of the electrodes within all-solid components. With this model, the charge-discharge cycling of an SSB is simulated with a focus on the interaction ... Read More
Modern integrated circuits are available as plastic encapsulated microcircuits (PEM). These devices are molded out of polymeric materials and epoxy resins in order to protect the internal semiconductors. Unfortunately, polymeric mold compounds absorb moisture when exposed to a humid ... Read More
This model shows how to use the scattered field formulation to compute the transmission coefficient for impinging P and S plane elastic waves onto a finite size phononic crystal. The transmission tends to zero in the frequency range corresponding to P- and S-wave band gaps, as ... Read More
This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ... Read More
An AC contactor is a particular type of magnetic switch device, which is activated by a primary coil fed by an alternating current. Unlike DC switches, such devices can suffer from a tendency to reopen when the AC current crosses zero. The addition of a shading coil that supports ... Read More
In this tutorial example, the concepts of Component Mode Synthesis (CMS) are introduced through a simple solid model of a cantilever beam. Parts of the beam are reduced by the CMS technique. It is, furthermore, shown how CMS can be used to represent both the static and dynamic behavior ... Read More
In his example, the lowest natural frequency of a 3D bracket are maximized using shape optimization. Read More
