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.

Plastic Deformation During the Expansion of a Biomedical Stent

A stent is a wire-mesh tube used to open a coronary artery during angioplasty, a process for the removal or compression of plaque. Their design is of significance for percutaneous transluminal angioplasty with stenting. During this procedure, a stent is deployed into the blood vessel by ... Read More

Hyperelastic Seal

In this model you study the force-deflection relation of a car door seal made from a soft rubber material. The model uses a hyperelastic material model together with formulations that can account for the large deformations and contact conditions. Read More

Compression of an Elastoplastic Pipe

In offshore applications, it is sometimes necessary to quickly seal a pipe as part of the prevention of a blowout. This example shows a simulation, in which a circular pipe is squeezed between two flat stiff indenters. The model serves as an example of an analysis with very large plastic ... Read More

Necking of an Elastoplastic Metal Bar

A circular metal bar of elasto-plastic material with nonlinear isotropic hardening behavior is subjected to uniaxial tension. Affected by significant stresses the bar experiences high plasticity. The phenomenon of necking is captured and its growth is accurately simulated. The change in ... Read More

Water Balloon Inflation

The process of filling a water balloon is a vivid example for the interaction of fluid pressure and a nonlinear structural material. This model demonstrates how straightforward a FSI simulation model is set up in COMSOL. Read More

Arterial Wall Mechanics

This model shows how to implement an anisotropic hyperelastic material for modeling collagenous soft tissue in arterial walls. The hyperelastic material model, called Holzapfel-Gasser-Ogden material, is based on the article: Holzapfel, G. A., Gasser, T. C., & Ogden, R. W. (2000). A new ... Read More

Die Forming

Die forming is a widespread sheet metal forming manufacturing process. The workpiece, usually a metal sheet, is permanently reshaped around a die through plastic deformation by forming and drawing processes. Simulations can be carried out in order to avoid cracks, tears, wrinkles, too ... Read More

Cracking of a Notched Beam

In this example, two model for brittle damage are used to evaluate the fracture of a notched concrete beam subjected to three point bending. The results are compared with experimental data. Read More

Stress Analysis of a Pressure Vessel

A pressure vessel is designed to hold liquids or gases at substantially higher or lower pressures than the ambient pressure. A high pressure difference requires a correct design in order to avoid catastrophic failures. The Stress Analysis of a Pressure Vessel app is an example of how ... Read More

Adhesion and Decohesion of Indenting Ball

A steel ball is pressed down against a rubber membrane. When the contact pressure exceeds a certain value, the two parts start sticking together. When the ball is retracted, the membrane is pulled upwards in the bonded region. During the retraction, the bond is partially broken. This ... Read More
