In accordance with our Quality Policy, COMSOL maintains a library of hundreds of documented model examples that are regularly tested against the latest version of the COMSOL Multiphysics® software, including benchmark problems from ASME and NAFEMS, as well as TEAM problems.
Our Verification and Validation (V&V) test suite provides consistently accurate solutions that are compared against analytical results and established benchmark data. The documented models below are part of the COMSOL Multiphysics® software’s built-in Application Libraries. They include reference values and sources for a wide range of benchmarks, as well as step-by-step instructions to reproduce the expected results on your own computer. You can use these models not only to document your software quality assurance (SQA) and numerical code verification (NCV) efforts, but also as part of an in-house training program.
This example demonstrates how to set up the classical external-flow problem of solving for the high-speed, compressible, turbulent flow over the ONERA-M6 wing. The problem involves finding a steady-state solution of the flow field around the 3D, swept wing geometry, immersed in a ... Read More
This benchmark models two-phase flow in a porous medium in 1D, where the flow can be analytically described by the Buckley-Leverett equation. Read More
The standard biventricular cardiac model is used to show how to set up fiber directions in a complex geometry. The fibers are then used to model the large deformation of the myocardium with the Holzapfel-Gasser-Ogden anisotropic material model. The Aliev-Panfilov equations are included ... Read More
Cyclones are used in a variety of applications ranging from the mining industry to vacuum cleaners. The flow in a cyclone is characterized by a very strong swirl, which makes it difficult to simulate. In this tutorial example, the v2-f turbulence model is used to simulate the flow in a ...

The flow around the Eppler 387 airfoil is computed with the SST turbulence model both with and without the transition model. The reuslts are compared with experimental values. 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
This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are ... Read More
This tutorial example shows how to use the Electric Currents in Shells interface together with Magnetic Field interface to compute the resistance and inductance of a planar PCB coil in the stationary regime. Read More
Polymer hydrogels consist of a crosslinked network of long-chained polymers that has imbibed a large number of solvent molecules. Such materials are used in many biomedical applications, such as targeted drug delivery, tissue engineering, and stimuli-sensitive actuators. This benchmark ... Read More
This model solves Poisson's equation on a unit disk with a point source at the origin. The mesh density is higher close to the origin to resolve the singularity. The computed solution is compared to the analytical solution. Read More
