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.
This tutorial model shows the setup of a 2D axisymmetric stress analysis, through contact, of a 3D threaded pipe fitting. The example involves synchronizing the 3D Solid Edge® geometry and selections, which specify the faces in contact, with the 2D geometry in COMSOL ... Read More
This model demonstrates the use of boundary element method in the Electromagnetic Waves, Boundary Element interface to model an optical Yagi-Uda antenna. The antenna is driven by an electrical point dipole, which is implemented through the background field. The field distribution around ... Read More
This model simulates a plasma at medium pressure (2 torr) where the plasma is still not in local thermodynamic equilibrium. At low pressures the two temperatures are decoupled but as the pressure increases the temperatures tend towards the same limit. Read More
A cooling flange in a chemical process is used to cool the process fluid, which flows through the flange. The surrounding air cools the flange via natural convection. In the stationary model, the forced convection to the process fluid is modeled using a constant heat transfer ... Read More
This tutorial demonstrates how to compute the response of an ultrasonic car parking sensor transducer coupling Pressure Acoustics, Frequency Domain, Solid Mechanics, and Piezoelectric Materials. The far-field radiation pattern of the transducer is then used as a source for a Ray ... Read More
Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using ... Read More
This tutorial shows how to model car cabin acoustics using a low frequency FEM solution concatenated with a high frequency ray solution. The source is a tweeter located in the dashboard corner, which is modeled as a lumped loudspeaker coupled to an electric circuit. To accurately include ... Read More
The fluid flow in seals causes a strong restoring radial force, opposing the shaft motion. Also, there is a cross coupled force due to the axial variation of the circumferential flow. The first type of force always has a stabilizing effect on the rotor, whereas the second one in certain ... Read More
The heat transfer rate and hydraulic resistance of a three dimensional heat exchanger is optimized in the laminar flow regime. Read More
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... Read More
