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 calculates the spectral properties of a 3D optical ring resonator. The model demonstrates how to use parts from the Wave Optics Parts Library and how to setup the Field Continuity boundary condition at boundaries, where there is a jump in the predefined phase approximation. Read More
This model demonstrates the Lithium-Ion Battery interface for studying the discharge and charge of a lithium-ion battery for a given set of material properties. The geometry is in one dimension and the model is isothermal. Battery developers can use the model to investigate the influence ... Read More
When producing glass, the glass melt is cooled down through radiation to form the final shape, subjecting it to stresses. Numerical treatment of radiative heat transfer, using the Radiative Transfer Equation (RTE), helps to optimize this process. COMSOL Multiphysics provides three ... Read More
This is one of the two models from the blog post about heat transfer in the subsurface: Coupling Heat Transfer with Subsurface Porous Media Flow Note: Poroelasticity is not included here. Read More
Electronic equipment often has to be certified to function after having been subjected to a specified shock load. In this example, the effect of an 50g 11ms half sine shock on a circuit board is investigated using response spectrum analysis. The results are compared with a time domain ... Read More
The goal with this app is to explain experimental electrochemical impedance spectroscopy (EIS) measurements and to show how you can use a simulation app, along with measurements, to estimate the properties of lithium-ion batteries. The app takes measurements from an EIS experiment and ... Read More
In this example, the mechanical impact of a golf club hitting a golf ball is studied. The contact between the two parts is modeled using a viscous penalty formulation to stabilize the dynamic event. To properly model the large deformation, the golf ball is defined using a hyperelastic ... Read More
This tutorial shows how to set up a multi-element objective lens. The chosen lens is the Double Gauss described in 'Modern Lens Design (2nd edition)', by W. Smith, 2005, pg 323. The tutorial demonstrates how to create a geometry sequence using the 'Spherical Lens 3D' part found in the ... Read More
This is a model of the heating process in a microwave oven. The distributed heat source is computed in a stationary, frequency-domain electromagnetic analysis. This is followed by a transient heat transfer simulation showing how the heat redistributes in the food. Read More
Ion-exchange is a powerful method to separate proteins from solutions and is today readily used in biotechnological and pharmaceutical industry. This model simulates an ion-exchange column for protein adsorption. The fluid phase contains four components: two proteins, solvent, and one ... Read More
