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. To download the MPH-files, log in or create a COMSOL Access account that is associated with a valid COMSOL license. 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.

Truck Mounted Crane Analyzer

This app demonstrates the following: * Using the knob form object * Updating the geometry by rotating a knob * Provides info if the results are above or below certain critical values Many trucks are equipped with cranes for handling loads and such cranes have a number of hydraulic ... Read More

Removing Details in Model Geometries

This model illustrates how to use the *Remove Details* operation to automatically find and remove small details from a model geometry. Read More

Semibatch Polymerization

As reactant monomer converts into polymer chains, the density of the reacting mixture often changes notably. In this example you will look at how this effect impacts the total production of polymer in a process. The liquid phase polymerization takes place in a semibatch reactor, where ... Read More

Converting Point Cloud Data to Surfaces and Solids

Not all analysis projects start with a CAD model. Sometimes the only data you have available is a set of points, also known as a point cloud. The examples files available here illustrate how point cloud data can be converted to geometry models that can be used for simulation in the ... Read More

Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. Read More

Beam Section Calculator (Using LiveLink™ for Excel®)

This app demonstrates the following: * Reading and importing data from an Excel®-file * Exporting data to an Excel®-file * Light theme The app computes the beam section properties and true stress distribution in a designated steel beam section. A broad range of American and European ... Read More

Ply Drop-Off in a Composite Panel

Ply drop-off often occurs in composite laminates to tailor the laminate thickness based on the loading requirements. This example illustrates the modeling of ply drop-off in a composite panel. The panel considered for the analysis has symmetric angle-ply layup with three sections: thick, ... Read More

Modeling Current Distribution in a 3D Lead-Acid Battery Grid Battery

This 3D model example demonstrates the use of the Lead-Acid Battery interface for modeling current distribution in full cell employing a lead-acid battery chemistry. The lead acid battery chemistry uses PbO2 as the positive porous electrode and Pb as the negative porous electrode and ... Read More

Walking Instability in a Washing Machine

Walking instability, due to non-uniform distribution of clothes, is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are more popular because of their high efficiency in spite of high manufacturing cost. ... Read More

Critical Speed of a Dual Rotor System

Due to the demand for larger power with a smaller size, dual-shaft systems with intershaft bearings are becoming a standard configuration for gas turbine engines. Such systems consist of two coaxial rotors running at different speeds, interlinked through a multi-spool bearing. In this ... Read More
