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.
In this example, a settlement and heave analysis of a shallow foundation resting on an unsaturated soil stratum is conducted with the Modified Cam-Clay and Extended Barcelona Basic soil models. The effect of pore suction due to movements in the phreatic line and the resulting settlement ... Mehr lesen
This example reproduces a NAFEMS benchmark in which a plate with an angle crack is subjected to tensile loading. The J-integral is calculated and the stress intensity factors for Mode I and Mode II are compared to the benchmark results for several crack angles. Mehr lesen
When modeling the propagation of charged particle beams at high currents and relativistic speeds, the space charge and beam current create significant electric and magnetic forces that tend to expand and focus the beam, respectively. The Charged Particle Tracing interface uses an ... Mehr lesen
In this example, a heat-conduction problem with phase change in a porous material is solved, and the results are compared with the analytical solution, also known as the Lunardini solution. This is the first benchmark case from the InterFrost project, which was initiated to compare ... Mehr lesen
This tutorial shows how to set up a ray release based on the incident electric field at a boundary. First the Electomagnetic Waves, Frequency Domain interface is used to solve for the electric field of a plane wave. Then rays are released with initial intensity and polarization matching ...

Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... Mehr lesen
This example describes the cooling and solidification, from melt to solid metal, in a continuous casting process. The model includes nonisothermal properties, temperature distribution, flow field, and phase change. This example uses the arbritrary Lagrangian-Eulerian method for modeling ... Mehr lesen
The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... Mehr lesen
This model simulates the isotropic compression of naturally structured and artificially structured clays using the Modified Structured Cam-Clay (MSCC) material model. The aim of the example is to reproduce the compression behavior given in a benchmark for four structured clays. Mehr lesen
This example presents a homogenized model of a corrugated sheet based on a unit cell approach. The numerically obtained equivalent stiffness matrices are compared with various analytical models. Two corrugation profiles, trapezoidal and round, are considered in this example. Mehr lesen
