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 describes how to simulate the self-lubricating phenomenon of a liquid lubricant in a journal bearing. A porous bushing is press-fitted to a bearing and saturated with a lubricant. It acts as a reservoir for the redistribution of the thin film of lubricant between regions of ... Read More
This application shows how a battery cell exposed to a hybrid electric vehicle drive cycle can be investigated with the Lithium-Ion Battery interface in COMSOL. This model predicts the battery behavior to make comparisons of the monitored properties. They can be used to understand the ... Read More
This example explores the shift in natural frequencies caused by changing the temperature. One study investigates a doubly clamped beam where both ends are fixed, while the other study looks at a cantilever beam where only one end is fixed. The following effects are studied: Stress ... 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
This is a model of the secondary current distribution in a zinc electrowinning cell. The model investigates the impact on the current distribution when changing the electrode alignment in a parametric study. The geometry is in 2D. Read More
This model determines the reflection coefficient of plane acoustic waves, at different frequencies and at different angles of incidence, off a water-sediment interface. The ability of the Poroelasitc Waves interface to model the coupled acoustic and elastic wave in any porous substance ... Read More
This entry is a compilation of some examples from DIN EN 1991-1-2 (Actions on structures exposed to fire). Models that are included: 1. Cooling (HT) 2. Heating (HT) 3. Heat transfer through multiple layers (HT) 4. Thermal elongation (SME, thermal stress) 5. Thermal expansion (SME, HT, ... Read More
The model features the optimization of the geometry of a complex-shaped coil similar to those for induction heating applications. The geometry if fully built and parametrized in COMSOL Multiphysics (taking advantage of Geometry Parts; geometrical construction requires Design Module). The ... Read More
This model simulates a 16-level, first-order, focusing Fresnel lens with 50 µm diameter and 150 µm focal length. In one simulation, the Electromagnetic Waves, Frequency Domain interface computes the electric field in the Fresnel lens and the surrounding air domain extended to the focal ... Read More
