The Model Gallery features COMSOL Multiphysics model files from a wide variety of application areas including the electrical, mechanical, fluid, and chemical disciplines. You can download ready-to-use models and step-by-step instructions for building the model, and use these as a starting point for your own modeling work. Use the Quick Search to find models relevant to your area of expertise, and login or create a COMSOL Access account that is associated with a valid COMSOL license to download the model files.

Scordelis-Lo Roof Shell Benchmark

In this example a thin curved membrane is built and solved using the Shell interface. This model is a widely used benchmark model denoted the Scordelis-Lo roof. The computed maximum z-deformation is compared with the value given in Proposed Standard Set of Problems to Test Finite Element Accuracy, Finite Elements in Analysis and Design, 1985.

Structural Integrity of a Hip Replacement

The most common reason that people have hip-replacement surgery is due to the wearing down of the hip joint that results from osteoarthritis. Other conditions, such as rheumatoid arthritis (a chronic inflammatory disease that causes joint pain, stiffness, and swelling), avascular necrosis (loss of bone caused by insufficient blood supply), injury, and bone tumors can also lead to the breakdown of ...

Fuel Cell Bipolar Plate

A fuel cell stack operates at temperatures just below 100 °C, which means that it has to be heated at start-up. The fuel cell stack consists of unit cell of anode, membrane, and cathode connected in series through bipolar plates. This study presents a model that couples the thermal and structural deformations in a fuel cell bipolar plate. The magnitude and position of the thermal stresses ...

Stress Relaxation of a Viscoelastic Tube

This model studies the temperature effects on the viscoelastic stress relaxation in a long thick-walled cylinder. In particular, decay of the stresses under the influence of the temperature field during a period of two hours is studied. A four-term generalized Maxwell model represents the material.

Hertzian Contact

A long elastic cylinder resting on a flat rigid foundation is analyzed. The cylinder is subjected to a uniform load along its top. The contact pressure distribution is compared with the analytical solution

Various Analyses of an Elbow Bracket

The component depicted in this model is part of a support mechanism and is subjected to various mechanical loads. This tutorial model takes you through the steps to carry out a detailed analysis of the part using the Structural Mechanics Module. In the various parts of the example you are introduced to using the available basic analysis types, together with numerous postprocessing possibilities. ...

Postbuckling Analysis of a Hinged Cylindrical Shell

The model studied is a benchmark for a hinged cylindrical panel subjected to a point load at its center. A linear buckling analysis predicts the critical buckling load. Such an analysis will however not give any information about what happens at loads higher than the critical load. Tracing the solution after the critical load is called a postbuckling analysis. This model uses the Shell interface.

Assembly with a Hinge

In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of freedom. Examples of such connections are ball joints, hinges, and different types of bearings. If the details of the connection are not the subjects of the analysis, it is often possible to model the connection using the Rigid Connector feature in COMSOL ...

In-Plane Framework with Discrete Mass and Mass Moment of Inertia

In this model, you build and solve a 2D beam model using the 2D Structural Mechanics Beam interface. This model describes the eigenfrequency analysis of a simple geometry. A point mass and point mass moment of inertia are used in the model. The two first eigenfrequencies are compared with the values given by an analytical expression.

Absorptive Muffler with Shells

This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the muffler. Finally, the eigenmodes of a pure structural problem is analyzed and the modes compared to peaks in ...
