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 is about the modeling of the fiber drawing process. Thermal fiber drawing is a process in which a comparatively thicker structure is heated and drawn into extended lengths of microstructured fiber. This process is done by passing them through the furnace and pulling them ... Read More
A 3D model of an acoustic trap in a glass capillary with a bias flow through the capillary. The acoustics is actuated by an oscillating electric potential across a piezoelectric transducer, inducing mechanical vibrations in the solid, and an acoustic pressure field in the fluid. The heat ... Read More
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
Thermoelectric coolers are widely used for electronics cooling in various application areas, ranging from consumer products to spacecraft design. The thermoelectric modules are a common application of thermoelectricity in cooling engineering. They consist of several thermoelectric legs ... Read More
This example models a split-and-recombine mixer channel in which a tracer fluid is introduced and mixed by multilamination. Diffusion is removed from the model using an extremely low diffusion coefficient so that any numerical diffusion can be studied in the lamination interfaces. The ... Read More
This model demonstrates how to define Earth properties that are spatially varying on the planet. A satellite in orbit experiences solar, albedo, and planetary infrared (IR) loads, where albedo and planetary IR can vary with latitude and longitude. In this example, these inputs are read ...

This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... Read More
This model demonstrates the use of the Heat and Moisture Flow features for the simulation of superheated steam drying of a wood particle. A nonequilibrium formulation is used to compute the transport of the liquid water and vapor phases in the wood particle. Reference: Le, K. H., ... Read More
Computing molecular flows in arbitrary geometries produces complex integral equations that are very difficult to compute analytically. Analytic solutions are, therefore, only available for simple geometries. One of the earliest problems solved was that of gas flow through tubes of ... Read More
This tutorial model demonstrates the use of the Moisture Flow coupling node to account for the Stefan flow in moist air, over an evaporation surface. The effects on the velocity field and vapor concentration are presented with different ambient temperature conditions. Read More
