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 entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... Read More
This model shows how shape optimization can be used to design an acoustic demultiplexer. A demultiplexer is a data distributing device, in this case it will distribute acoustic energy. The geometry consists of a circular domain with one input port and two output ports. The domain has the ... Read More
This example extends the corrosion protection system analysis of the single oil platform example by modeling the influence of multiple oil platforms placed in an array. The use of the Current Distribution on Edges, BEM interface significantly reduces the problem size and computational ... Read More
This 3D model example demonstrates the use of the Primary Current Distribution interface for modeling current distributions in electrochemical cells. In primary current distribution, the potential losses due to electrode kinetics and mass transport are assumed to be negligible, and ... Read More
The thin low permittivity gap boundary condition is meant to approximate a thin layer of material with low relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the thin low permittivity gap ... Read More
The dielectric shielding boundary condition is meant to approximate a thin layer of material with high relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the dielectric shielding boundary ... Read More
Power lines are commonly used as a means of transmitting electrical power across large distances. In this tutorial, towers transmitting high voltage three-phase AC power are modeled, and the resulting electric field is computed. The towers have two shielding lines. The model also ... Read More
A silicon wafer is heated up by a laser that moves radially in and out over time. In addition, the wafer itself is rotated on its stage. The incident heat flux from the laser is modeled as a spatially distributed heat source on the surface. The transient thermal response of the wafer is ... Read More
This example solves the problem of finding the optimal thickness profile of a flywheel, so that the moment of inertia is maximized without increasing the mass or the maximum stress in the flywheel. Read More
Composite materials are often used in structural applications, where the ability to tailor properties such as stiffness and strength make them attractive compared to traditional engineering materials. In addition to structural applications, composites are also used in applications where ... Read More
