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.
Commercial heat exchangers often feature a complex design. It is significantly easier to build a design with new CAD parameters than to build designs with novel topologies. This model demonstrate how to optimize the size and position of the tubes in a tube and shell heat exchanger. It is ... 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
This model studies the structural deformation of an aircraft fuselage structure subjected to buckling loads. The structure is an assembly of panels and skin connected by rivets. The Fasteners feature sets up a large number of connections and computes the forces acting on each rivet. Read More
Soft permanent magnets like AlNiCo are easily demagnetized if handled incorrectly. This is a demonstration of how to model the self-demagnetization of a cylindrical AlNiCo magnet when moved out of its associated/protective magnetic circuit. The modeling is performed in three steps: The ... Read More
A classic way of estimating pi is by using the Monte Carlo method. This involves randomly placing points inside a square and counting how many lie within a circle inscribed in the square. The ratio of points inside the circle to the number of points in total can be used to approximate ... 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
Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Read More
Modeling curing is important in a wide variety of applications such as for devices utilizing polymer materials, rubber materials, plastics, and concrete. Curing is usually an exothermic reaction. In the current example, curing of butyl rubber is studied in a 3D mold for an automotive ... Read More
The Curve Digitizer application can be used to digitize/extract curves from images. This application provides an easy way to digitize a variety of 1D plots with different axes in Cartesian or Polar coordinate system. After a curve image is imported, the digitization is done in a few ... Read More
This tutorial shows how to model a miniaturized magnetostrictive antenna developed for use inside living cells. The stress in the antenna, the magnetic flux density, the current density, and the displacement of the tip of the device are investigated at the resonance frequency. Read More
