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.
Wind turbines are an increasingly popular source of renewable energy. As such, the design, analysis and manufacture of wind turbines are important to the energy industry. The turbine blades are critical components of a wind turbine. When generating electric power through rotation, they ... Read More
In this example, drug-release from a biomaterial matrix to damaged cell tissue is modeled. Specifically, a nerve guide delivers a regenerating drug to damaged nerve ends. The model involves detailed drug release kinetics, with rate expressions handling drug dissociation/association ... Read More
Applying an electric field across a suspension of immiscible liquids may stimulate droplets of the same phase to coalesce. The method known as electrocoalescence has important applications, for instance, in the separation of oil from water. To model electrocoalescence, you need to solve ... Read More
Model of the sound radiation from a circular duct with uniform flow. The convected acoustic problem is described using the linearized potential flow equations, solved in the frequency domain. The acoustic inlet is treated including higher order modes using the Port boundary condition and ... Read More
This model shows how to model the avalanche breakdown due to the impact ionization in a Silicon Carbide diode. The current-voltage (I-V) characteristics of the device are presented as well as the electric field distribution plot. Furthermore, the carrier generation term has been computed ... Read More
This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... Read More
This example is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... Read More
In this example, the micromechanical properties of a piezoelectric fiber composite are studied. The homogenized electromechanical properties of the composite are derived from the individual microscopic properties of matrix and fiber. Read More
This model analyses the noise generated by an electric motor during its operation at different speeds of rotation. The type of electric motor analyzed, a permanent magnet synchronous motor (PMSM) uses permanent magnets in the rotor and a variable frequency current traveling through the ... Read More
This tutorial illustrates how to use the Uncertainty Quantification (UQ) functionality to answer questions regarding sensitivity and reliability of a flow reactor with thermal decomposition. The tutorial investigates what uncertainties in parameters dominates the survival of a nutrient ... Read More
