Notez que de nombreux exemples présentés ici sont également accessibles via la Bibliothèques d'Applications intégrée au logiciel COMSOL Multiphysics® et disponible à partir du menu Fichier.
Beam theories are well-developed for slender structures with homogeneous materials and isotropic cross-sections. The traditional beam theories do no apply to beams made of different materials in the cross-section. Therefore, a homogenization-based numerical model is needed to compute ... En savoir plus
This example shows how to set up an ionic polymer-metal composite (IPMC) as an actuator for a robotic manta ray. Two IPCM beams are integrated into the fin and can be controlled independently. The chemomechanical effect is achieved with the Shrinkage and Swelling multiphysics ... En savoir plus
This model shows how to model a simple Metal–Insulator–Metal (MIM) diode. The two metal electrodes are defined on each side using the Metal Contact feature. Two studies were performed: one without quantum tunneling across the potential barrier and the other including it, using the WKB ... En savoir plus
This tutorial demonstrates how to use the temperature and relative humidity computed by the simulation of heat and moisture transport in an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction computes a mold index M by solving an ... En savoir plus
The example shows how to generate a discharge model from the Reaction Engineering interface with a self-defined discharge chemistry. It reproduces the library model 127181 (Double-Headed Streamer in Parallel-Plate Electrodes). En savoir plus
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Edges. In this model, three layered shells are connected to heat domains by edges at difference locations related to the heat domains. The results obtained with the Heat ... En savoir plus
This file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of x- and y-coordinates. The data is of the Matterhorn, a European mountain located in the Alps. In ...

In this example, the natural frequencies of a double hat beam are studied. The beam is made of two thin steel plates, joined together by spot welds along the flanges. The Spot Welds feature sets up multiple mesh-independent connections between the shells. En savoir plus
When you are working with foreign CAD or ECAD data, such as files in the STEP, GDS, or IGES file formats, or any of the other supported formats, you may think that you need to re-import a new CAD file and start your modeling over from scratch if you want to study a change in size or ...

This example illustrates the modeling of a tensegrity table. The table is made of two rigid bodies connected through a central wire and four outer wires. Two cases are analyzed. In the first case, the top of the table is loaded with vertically downward acting load of varying magnitude. ... En savoir plus
