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 example Stiffness Analysis of a Communication Mast’s Diagonal Mounting in the COMSOL Multiphysics Model Library shows how you can modify a 3D CAD model to improve its performance. In that case, the applied changes were based solely on the analyst’s experience with similar structures. ... Read More
This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... Read More
This model demonstrates how to model phenomena defined in different dimensions in a fully coupled manner using COMSOL Multiphysics. Whereas in most cases the reaction rate expression is defined as a function of the concentrations of the reactants and products, in adsorption reactions ... Read More
This model illustrates the working principle of an axial homopolar induction bearing. An electrically conducting rotor rotating in a magnetic field produced by a permanent magnets induces eddy currents on the conducting rotor. The eddy currents, in turn, produce a magnetic field that ... Read More
This tutorial model shows how to import a 3D scanned geometry of a human head and torso and compute the head related transfer function (HRTF). The scan is imported as a .stl file and converted into a COMSOL geometry. The HRTF is computed using the reciprocity principle, locating the ... Read More
This model demonstrates how to simulate a metasurface beam deflector that uses anomalous refraction. The structure itself is a repeated array of six posts (so-called meta elements). The periodicity of the individual posts is 500 nm, so the full structure of six posts is 3 um wide. The ... Read More
Fluids that move through pore spaces in an aquifer or reservoir can shield the porous medium from stress because they bear part of the load from, for instance, overlying rocks, sediments, fluids, and buildings. Withdrawing fluids from the pore space increases the stress the solids bear, ... Read More
A spherical water-rich load (potato) is placed on the rotating glass tray of a microwave oven some distance from the center of rotation. 1 kW of 2.45 GHz microwave power is applied via a waveguide feed. The plate rotates at 9 degrees per second. The heat transfer model involves the ... Read More
This tutorial model of a two-hot-arm thermal actuator couples three different physics phenomena: electric current conduction, heat conduction with heat generation, and structural stresses and strains due to thermal expansion. The model exists in three versions: Joule Heating of a ... Read More
Nowadays, there is a trend to manufacture wheel rim made up of a composite material instead of aluminum. The primary reason is to have lower values of unsprung mass which leads to faster response time and thus better acceleration, braking and cornering performances. Typically a carbon ... Read More
