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.
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Read More
This example shows how to model tissue ablation through applying RF radiation. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Study Radiofrequency Tissue Ablation Using Simulation". Read More
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. Read More
This model presents the transient modeling of a coaxial magnetic bearing using permanent magnets. The coaxial magnetic bearing is advantageous over the conventional mechanical gear mainly because of minimum noise, maintenance free operation, overload protection and physical isolation ... Read More
Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... Read More
The AC/DC magnetic interfaces support material models defined in external C code. You can access external material functions, written in C code, which have been compiled into a shared library. By writing a wrapper function in C code, you can also use material functions written in another ... Read More
A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... Read More
Freefrom optics has generated renewed interest due to advances in fabrication and manufacturing technology. In this Application Library example, we are going to look at a specific design called the Alvarez lens where two complementary conic surfaces are shifted laterally with respect to ... Read More
This model showcases the broadband optimization for the Microstructured antireflective coatings that are modeled in the model (#99011). Following are the parameters that are optimized: Rectangular microstructure: Height and width of the rectangular microstructure. Pyramidal ... Read More
Electrical cables, also called transmission lines, are used everywhere in the modern world to transmit both power and data. These cables carry electromagnetic energy, but instead of dealing with the full complexity of the electromagnetic fields, they are more commonly classified ... Read More
