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.
Chemical engineering students can model a nonideal tubular reactor, including radial and axial variations in temperature and composition, and investigate the impact of different operating conditions with this easy-to-use app. The process described by the Tubular Reactor with ... Read More
This tubular reactor application, together with its associated embedded model, demonstrates how the computational speed can be increased with the use of a surrogate model, as opposed to a fully-fledged finite element model. A surrogate model is a simpler, usually computationally cheaper ... Read More
This model solves Poisson's equation on a unit disk with a point source at the origin. The mesh density is higher close to the origin to resolve the singularity. The computed solution is compared to the analytical solution. Read More
Modeling the electrical activity in cardiac tissue is an important step in understanding the patterns of contractions and dilations in the heart. The heart produces rhythmic electrical pulses, which trigger the mechanical contractions of the muscle. A number of heart conditions involve ... Read More
This tutorial analyzes the resistive heating (Joule heating) of a busbar assembly designed to conduct a direct current from a current source to the anode in an electrolysis process. Read More
This example exemplifies how to model thermal ablation by taking into account material removal. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Thermal Ablation for Material Removal". Read More
This model simulates the pressure wave propagation in a muffler for a combustion engine. It uses a general approach for analysis of damping of the propagation of harmonic pressure waves. The model is solved in the frequency domain and provides efficient damping in a frequency range of ... Read More
This example analyzes the deformation of a feeder clamp under stress. The clamp secures a feeder that carries high-frequency electromagnetic fields, and it’s important that it remains as straight as possible. Forces on the clamp include both those from the feeder as well as those on the ... Read More
This tutorial demonstrates how to partition a 3D part to create a swept mesh. The example explores different strategies for partitioning the geometry, and demonstrates how to combine hexahedral and tetrahedral meshes. Read More
The incompressible boundary layer on a flat plate in the absence of a pressure gradient is usually referred to as the Blasius boundary layer. The steady, laminar boundary layer developing downstream of the leading edge eventually becomes unstable to Tollmien-Schlichting waves and finally ... Read More
