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 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 ...

When electrons are emitted from a heated cathode in a plane parallel vacuum diode, they contribute to the space charge density in the diode, which in turn affects the electric potential distribution. If the potential difference between the cathode and the anode is not sufficiently large, ... 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
A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... 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 tutorial simulates a standard test and benchmark model for nonreflecting conditions and sponge layers for linearized Euler-like systems. It involves the propagation of a transient Gaussian pulse in a 2D uniform flow. The Convected Wave Equation, Time Explicit interface solves the ... Mehr lesen
This benchmark model computes the valence band structure of an unstrained and a strained bulk GaN wurtzite crystal, as a tutorial for users who wish to set up multiple wave function components with the Schrödinger Equation interface. The model follows the formulation given in the ... Mehr lesen
This example describes how to simulate the self-lubricating phenomenon of a liquid lubricant in a journal bearing. A porous bushing is press-fitted to a bearing and saturated with a lubricant. It acts as a reservoir for the redistribution of the thin film of lubricant between regions of ... Mehr lesen
An axisymmetric model of a rigid piston in an infinite baffle is used to exemplify the Exterior Field Calculation feature of the Acoustics Module. The radiation results provided by the COMSOL Multiphysics® software are compared to analytical results for the on-axis radiation ... Mehr lesen
Lead-acid batteries are widely used as starting batteries for various traction applications such as cars and trucks and so forth. The reason for this is the fairly low cost in combination with the performance robustness for a broad range of operating conditions. However, one drawback of ... Mehr lesen
