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.
In this example, the External Stress feature in the Solid Mechanics interface is used to provide the material model with the nonsymmetric stress required in the design of an elastic invisibility cloak. The cloak is a domain with special material properties aimed at shielding a region of ... Read More
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix. Periodic boundary conditions are applied to a unit cell of the particulate composite ... Read More
In this tutorial model, the flow in a pipe with a bend is computed using the Pipe Flow interface. The computed fluid load is used as input to a stress analysis in the Pipe Mechanics interface. Gravity loads from the pipe and fluid are also taken into account. Read More
This example studies a portion of the vascular system of a young child. The aorta and its ramified blood vessels are embedded in biological tissue. The pressure from the moving fluid deforms the blood vessel. The complete analysis consists of two distinct but coupled procedures: a fluid ... Read More
This is a tutorial example, showing how to work with pretensioned bolts. Various aspects of bolt modeling are explored: Modeling bolts as solids or by beams Connections of beams to solid components Bolts ended by nuts or by internal threads in the attached component Import of bolt and ... Read More
This is a benchmark model for a plane stress problem. The accuracy of the computed stress concentration is evaluated, and a mesh convergence study is performed for different element types. Read More
In this conceptual example, the soft impact between two elastic rings is modeled using the Solid Mechanics and Shell interfaces. One of the rings is given an initial velocity to initiate the impact event. Both rings are unconstrained and not subjected to any external forces. Contact is ... Read More
In this benchmark example, a semi-elliptical crack at the inner surface of a cylinder is studied. The inside of the cylinder and the crack faces are subjected to a pressure load. The J-integral is calculated along the crack front, and the stress intensity factor is then compared with the ... Read More
