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.
The TSSG process, namely Top-Seeded Solution Growth, is a method used to grow SiC single crystals. It has the advantages of lower growth temperature and high crystal quality. This model introduces the simulation method of the TSSG process, obtains the temperature distribution of the ... Read More
Bearing clearances should be kept minimum to avoid non-synchronous vibration of a rotor. However, a tight clearance reduces the durability of the bearing. This example illustrates modeling of the vibration induced by nonlinear contact for different radial clearances. It is shown that ... Read More
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 ... Read More
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. Read More
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... Read More
This tutorial model demonstrates the use of the Area Scaling Factor (ASF) in the Heat Transfer in Shells interface, to account for the curvature of the layers when applying heat fluxes and heat sources. The results obtained with the Heat Transfer in Shells interface applied to a ... Read More
This model demonstrates how to create a rotated helix geometry, i.e., a helix that is winded to form a torus. This is done sweeping a circle along a parametric curve. The radius of the torus and the radius of the coil are given as parameters as well as the number of windings of the coil. Read More
This model shows that the frequency response, i.e. admittance curve, of the SAW unit cell with IDT is in good agreement with the series resonance & antiresonance frequencies obtained from the eigenfrequency studies in the tutorial Surface Acoustic Wave Velocity Calculations from a ... Read More
Carbon corrosion is one of the important degradation mechanisms in a Polymer Electrolyte Membrane (PEM) fuel cells which predominantly occurs during start-up or shut down of the fuel cells. During carbon corrosion, carbon support to catalysts is compromised affecting the cell ... Read More
These models are featured in the blog post Analyze Violin Tone and Volume with Multiphysics Modeling. One applies acoustic-structure interaction to study how the air mode resonance is affected by the coupled vibrations in the violin body. The other uses a potential flow approximation to ...
