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.

Polymer Electrolyte Membrane Electrolyzer
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 ... Mehr lesen
Porous Absorber
This is a model of acoustic absorption by a porous acoustic open cell foam. In porous materials the sound propagates in a network of small interconnected pores. Because the dimensions of the pores are small, losses occur due to thermal conduction and viscous friction. Acoustic foams are ... Mehr lesen
Computing Q Factors and Resonant Frequencies of Cavity Resonators
A classic benchmark example in computational electromagnetics is to find the resonant frequency and Q-factor of a cavity with lossy walls. Here, models of rectangular, cylindrical, and spherical cavities are shown to be in agreement with analytic solutions. Mehr lesen
Airflow over an Ahmed Body
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 ... Mehr lesen
Steady-State 2D Heat Transfer with Conduction
This example shows a 2D steady-state thermal analysis including convection to a prescribed external (ambient) temperature. It is given as a benchmarking example. The benchmark result for the target location is a temperature of 18.25 C. The COMSOL Multiphysics model, using a default mesh ... Mehr lesen
Flow Around an Inclined NACA 0012 Airfoil
This model simulates the flow around an inclined NACA 0012 airfoil at different angles of attack using the SST turbulence model. The results show good agreement with the experimental lift data of Ladson and the pressure data of Gregory and O’Reilly. Mehr lesen
Axisymmetric Transient Heat Transfer
This is a benchmark model for an axisymmetric transient thermal analysis. The temperature on the boundaries changes from 0 degrees C to 1000 degrees C at the start of the simulation. The temperature at 190 s from the anlysis is compared with a NAFEMS benchmark solution. Mehr lesen
