In Übereinstimmung mit unserer Qualitätspolitik unterhält COMSOL eine Bibliothek aus hunderten dokumentierter Modellbeispiele, die regelmäßig mit der neuesten Version der COMSOL Multiphysics® Software getestet werden, einschließlich Benchmark-Probleme von ASME und NAFEMS sowie TEAM-Probleme.
Unsere Verification and Validation (V&V) Testsuite bietet konsistent genaue Lösungen, die mit Analyseergebnissen und etablierten Benchmark-Daten verglichen werden. Die folgenden dokumentierten Modelle sind Teil der in der COMSOL Multiphysics® Software integrierten Anwendungsbibliotheken. Sie beinhalten Referenzwerte und Quellen für eine Vielzahl von Benchmarks sowie eine Schritt-für-Schritt-Anleitung, um die erwarteten Ergebnisse auf dem eigenen Computer zu reproduzieren. Mit diesen Modellen können Sie nicht nur Ihre Aufwendungen für die Software-Qualitätssicherung (SQA) und die numerische Code-Verifikation (NCV) dokumentieren, sondern sie auch im Rahmen von internen Trainingsprogrammen einsetzen.
This example illustrates how to set up and solve a tank-in-series model in 0D using the Reaction Engineering interface. The model treats a series of three consecutive tank reactors. A feedback loop continuously adjusts the inlet concentration of the first tank to keep the concentration ... Mehr lesen
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 ... Mehr lesen
In this example, the Bergstrom–Bischoff material model is used to model the temperature and strain dependent behavior of High Density Polyethylene (HDPE) used, for example, to make liners for damaged pipes in oil and gas applications, or to make type IV hydrogen storage vessels for fuel ...

In this example, learn how to model two rotors connected by a spline coupling. The first rotor is a fixed cantilevered rotor and the second rotor is supported. The model assumes that only translational motion is coupled between the rotors through the coupling, while the rotations of both ... Mehr lesen
The small strain overlay material model captures the effect of high stiffness at low strain as well as the hysteresis under cyclic loading, which is a common effect for most soils. The formulation allows stiffness degradation with an increase in shear strain, and the full recovery of ... Mehr lesen
In this example, wrinkling is studied in a cylindrical membrane of nonuniform thickness under axial and pressure loading. The membrane is modeled as an incompressible Mooney–Rivlin material. During axial stretching, certain portions of the membrane undergo wrinkling; however, the ... Mehr lesen
Ultrahigh Molecular Weight (UHMW) Polyethylene is a material commonly employed in knee and hip joint replacements. The “small punch test” is designed to assess mechanical properties using very small samples, such that because of their size they can directly be explanted. This example ... Mehr lesen
The installation verification application can be used to help verify that your COMSOL Multiphysics® or COMSOL Server™ installation works as expected on your hardware platforms and operating systems. The app automatically loads and runs a suite of test models and compares the results with ... Mehr lesen
This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... Mehr lesen
This model simulates the propagation of a double-headed streamer in nitrogen at atmospheric pressure. Initially, electron-positive ion clusters were introduced between two parallel electrodes, subjecting the gas to a strong background electric field of 52 kV/cm. Subsequently, both the ... Mehr lesen
