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 isotropic volumetric growth and atrophy of soft biological tissues. The artery is represented by a cylinder that is stretched and compressed due to an applied axial load. As a result, the tissue undergoes growth and atrophy. Read More
Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... Read More
Learn how to repair, edit, and combine imported surface meshes in COMSOL Multiphysics®. This model demonstrates how to cut out a part of the upper jaw, remove elements from the mesh, and combine the meshes of the teeth and bone. To learn more about how this model is set up, see ... Read More
This example model demonstrates four different approaches for computing the integrals of fields over arbitrarily placed geometries that can be re-positioned without having to re-solve the model. This approach is also useful if you want to integrate the results of a model over different ... Read More
This example exemplifies how to optimize the design of a capacitor through optimization. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Changing the Dimensions of a Model Using Shape Optimization". Read More
This model is used in the blog post "Why Do Golf Balls Have Dimples?". The trajectory of a golf ball is compared to the trajectory of a smooth ball using the Events interface and a system of ODEs in a 0D component. Read More
When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ... Read More
This app allows you to simulate the action potential in a cell's membrane using the Hodgkin-Huxley model. As it is presented in the form of a simulation app, you can change the input parameters for potential, conductance, and membrane capacitance to study their effects on the dynamics ... Read More
The model used is the P2D model also called the Newman model. Parameter estimation is run using experimental data of driving cycles from healthy cells. The parameter values are determined for a confidence of 0.95 for each parameter. Parameter estimation is then run using data from ... Read More
This model compares the solution to the model equations of a tubular reactor using Danckwerts inlet and outlet conditions. A second almost identical model is defined with extra inlet and outlet sections where no reactions occur. The concentration at the beginning of the inlet section is ... Read More
