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 shows the analysis of a perforated plate loaded into the plastic regime. The purpose of the analysis is to demonstrate how plastic strains can be mapped between dissimilar meshes. Read More
The fabrication of a cup through powder compaction is simulated in this tutorial model. The powder compaction process is becoming common in the manufacturing industry, due to its potential for producing components of complex shape and high strength. Combining the Fleck–Kuhn–McMeeking ... Read More
This model demonstrates the inflation of a rubber balloon with four different hyperelastic material models. The results are compared with the analytical solution for a thin-walled, spherical vessel. Controlling the inflation of hyperelastic balloons is important in clinical ... Read More
The External Material functionality makes it possible to program your own material models for cases when the built-in material models are not sufficient. For structural mechanics, you have the possibility to either completely define the material model in a domain, or to add an inelastic ... Read More
A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield ... Read More
Diaphragm accumulators are essential components that store energy and regulate hydraulic systems. A flexible rubber diaphragm divides the hydraulic fluid from a compressible inert gas, typically nitrogen. These accumulators perform multiple tasks, such as temporarily storing hydraulic ... Read More
In this example, the Bergstrom–Boyce material model is used to capture the nonequilibrium behavior of carbon-black-filled chloroprene rubber under a strain history that alternates compression with relaxation. Results are verified against experimental and numerical results taken from ... Read More
Powder compaction is a popular manufacturing process not only in powder metallurgy, but also in the pharmaceutical industry. The Capped Drucker–Prager model is commonly used for simulating the compaction processes of pharmaceutical powders, where the material properties depend on the ... Read More
This example benchmarks a NAFEMS validation model of a friction contact problem with an elastoplastic material model. A thin metal sheet is forced into a die by a punch. Both the compressing displacement and the release of the punch are modeled in order to compute the forming angle (at ... Read More
This example shows the analysis of a perforated plate loaded into the plastic regime. Part of the example is a benchmark, which you can find in section 7.10 of The Finite Element Method by O.C. Zienkiewicz. The unloading of the plate and residual stresses are also studied. In a second ... Read More
