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 the behavior of a thermostat where a delay in its reaction has been implemented. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "How to Implement a Delay in Your Thermostat Simulation". Read More
PCB is fabricated by laminating multiple materials, such as FR-4, copper, and resin, which exhibit significantly different coefficients of thermal expansion (CTE). When subjected to heating, the differential thermal expansion among these layers induces interlaminar deformation mismatch, ... Read More
This example demonstrates how to apply inverse uncertainty quantification (IUQ) using the Uncertainty Quantification (UQ) Module in COMSOL Multiphysics to calibrate uncertain material properties of a resistor based on measurement data. When experimental data such as resistance values are ... Read More
This example exemplifies how you can export the data from your mesh and results to a text file. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Exporting Meshes and Solutions Using the Application Builder". Read More
This example of a simulation application shows how to add a user-defined license agreement, which you can use to protect applications that you publish and distribute. Read More
This app generates random surfaces based on imported CAD models. Surfaces can be created using Gaussian or uniform random fields, analytical expressions, or combinations of random and deterministic fields. The app provides extensive customization options for controlling roughness, ... Read More
This example simulates the electrolysis of CO2 on a roughened-Cu cathode surface in a CO2-saturated CsHCO3 electrolyte. It solves for the concentration of dissolved-CO2, Cs+, HCO3–, CO32–, H+, and OH– within the mass-transport boundary layer and accounts for the homogeneous (bi)carbonate ... Read More
This example demonstrates how to model a variable-angle tow (VAT) laminate in which the fiber orientation varies linearly along the global x-direction, with each layer assigned its own fiber angle. The results obtained using the Layered Shell interface are compared with a full 3D ... Read More
This example demonstrates the optimization of fiber orientation in a variable angle tow (VAT) laminate to maximize stiffness under prescribed loading and boundary conditions. The composite laminate consists of a single layer of carbon–PEEK composite with transversely isotropic material ... Read More
This model demonstrates how to solve delay differential equations in the context of modeling a population dynamics problem. To learn more about this model, see our accompanying blog post “Solving Delay Differential Equations to Model…Marmots? ”. Read More
