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.
Plasma discharges containing chlorine are commonly used to etch semiconductors and metals in microelectronics fabrication. This tutorial model studies chlorine plasma discharges using a global (volume-averaged) diffusion model. Global diffusion models can run simulations in a fraction ... 詳細を見る
The fabrication of a cup through powder compaction is simulated in this tutorial model. The powder compaction process is becoming common in the manufacturing industry, due to its potential for producing components of complex shape and high strength. Combining the Fleck–Kuhn–McMeeking ... 詳細を見る
This example demonstrates the wrinkling of a thin rectangular sheet stretched uniaxially. First, a static analysis is performed to determine the region of negative principal stresses without wrinkling. Next, a prestressed buckling analysis is carried out to find out the linearized ... 詳細を見る
Whenever dimensions in waveguides become small compared to the viscous and thermal boundary layers it is necessary to model acoustics using thermoacoustics. In the present model the thermoacoustic wave field in a shallow uniform waveguide is modeled and compared to an analytical solution. 詳細を見る
A square airbag made of a hyperelastic, compressible neo-Hookean material is inflated using pressurized air. Compressive stresses trigger wrinkling in some regions of the thin airbag. In this example, the wrinkling behavior is modeled using tension field theory, which gives a correct ... 詳細を見る
This benchmark example builds two models of a cross-bridge Kelvin resistor used for extracting the specific contact resistivity. The first model simulates the system in 3D, using the contact resistance feature built in the Semiconductor interface. The other model is a 2D approximation of ... 詳細を見る
Biotechnology is a rapidly growing area in the pharmaceutical sciences. One example of a clinical application is gene therapy, where it is possible to produce proteins in vivo, using the body’s own mechanisms for protein production. Major issues in gene delivery involve the transport of ... 詳細を見る
Zone electrophoresis (ZE) is an electrophoretic separation technique typically used for analyzing proteins, nucleic acids, and biopolymers. During the process, different species in a sample are transported in a continuous electrolyte buffer system, subject to a potential gradient. Due to ... 詳細を見る
This benchmark studies the nonlinear deformation of a spherical cap subjected to point load at center using 2D axisymmetric Solid Mechanics and Shell interfaces. The results from the Shell interface are compared with Solid Mechanics interface as well as with analytical results given in ... 詳細を見る
This example describes how to simulate the flow of a thin film of fluid in the gap between two rectangular plates, one of them with a porous facing, when the fluid is squeezed as a consequence of the relative motion between the plates. The model accounts for the ingress and egress of ... 詳細を見る
