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 example shows how to model carbonation, which is a type of sparging. Sparging is a mass transfer process between a gas and a liquid that is common in industry (such as beverage carbonation and photobioreactor applications) and at home (aquarium aeration). In the carbonation model, ... 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
This model demonstrates two approaches to model the acoustics in a generic nacelle with an acoustic liner and a background flow. The first method uses the Compressible Potential Flow and the Linearized Potential Flow, Frequency Domain interfaces, while the second, more detailed approach, ... Read More
This shows how a Gaussian beam incident on a periodic structure can be efficiently simulated. This could be applied to structured surfaces like metasurfaces or diffraction gratings. Because of superposition, only a single unit cell needs to be simulated. This can provide extremely ... Read More
This model illustrates how to simulate a periodic homogenization process in a space dependent chemical reactor model. This homogenization removes concentration gradients in the reactor at a set time interval. The model demonstrates a technique by which you can first stop the time ... 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 utilizes the thermoviscous acoustic interface in a sub-model to obtain detailed results for the transfer impedance of a perforated plate (including the thermal and viscous losses). The impedance is in turn used as an internal impedance in a pressure acoustic model of a ... Read More
This example demonstrates how to define the lid-driven cavity benchmark in the field of computational fluid dynamics. In the model setup, a 2D square cavity has a tangentially moving wall that induces a large vortex in the center of the cavity, and small vortices in the corners. The ... Read More
This model demonstrates how to set up a phase field damage multiphysics model to predict crack propagation in thermoelastic solids under large deformations. The crack-driving force depends on the principal stresses, which in turn depend on the temperature distribution in the solid ... Read More
The model has its emphasis on heat transport in a very small heat exchanger that is commonly used in the field of microelectromechanical systems (MEMS). In this case, it might be a reactive processes that needs heating. The heat exchanger itself is constructed by stacking several ... Read More
