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.
In a polymer electrolyte membrane electrolyzer cell (PEMEC), the two electrode compartments are separated by a polymer membrane. Liquid water is fed to the anode side, forming oxygen gas on the anode, and hydrogen gas on the cathode side, respectively. The respective designs of the ... 詳細を見る
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 ... 詳細を見る

In this benchmark model for blood flow in a centrifugal pump, simulations are performed for several flow rates and pump speeds. The modeled geometry is taken from the FDA’s Computational Round Robin and the results are in good agreement with the experimental data. The computed shear ... 詳細を見る
Reflective mufflers are best suited for the low-frequency range where only plane waves can propagate in the system, while dissipative mufflers with fibers are efficient in the mid- to high-frequency range. Dissipative mufflers based on flow losses, on the other hand, also work at low ... 詳細を見る
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is ... 詳細を見る
The Ahmed body represents a simplified, ground vehicle geometry of a bluff body type. Its shape is simple enough to allow for accurate flow simulation but retains some important practical features relevant to automobile bodies. This model describes how to calculate the turbulent flow ... 詳細を見る
