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.
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ...

This example shows how to create a time-limited and hardware-locked application. It is associated with the section "Time-Limited and Hardware-Locked Applications" in the Application Programming Guide En savoir plus
This model demonstrate how to simulate ray tracing in a pinhole camera viewing a solar eclipse. To keep the model dimensions in check, the Sun and Moon are approximated using planar discs with the appropriate angular size (~0.5 degree) relative to the pinhole. In this example, the ...

You can use the Method Editor in the Application Builder for creating methods that perform almost any type of modeling tasks, including geometry modeling. It is easy to miss the fact that methods can support recursion by having a method calling itself in a recursive loop. Here, we will ... En savoir plus
This model simulates a beam of light being split into components of different frequencies when passing through a medium where the refractive index depends on frequency. COMSOL-wise, the model showcases two important technical aspects: A user-defined implementation of the frequency ... En savoir plus
This example exemplifies how to model a Koch snowflake using the Application Builder. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Using the Application Builder to Create a Koch Snowflake". En savoir plus
This example of a simulation application shows how to add a user-defined license agreement, which you can use to protect applications that you publish and distribute. En savoir plus
This model is used on "Heat Transfer with Radiation in Participating Media and the Discrete Ordinates Method" to compare quadrature sets used in the method of discrete ordinates. To assess the performance of quadrature sets in complex geometries, results of incident irradiation and ... En savoir plus
This example shows how to model isotropic volumetric growth and atrophy of soft biological tissues. The artery is represented by a cylinder that is stretched and compressed due to an applied axial load. As a result, the tissue undergoes growth and atrophy. En savoir plus
The model remove details example v63.mph illustrates how to manually add the Remove Details operation and virtual operations to find and remove small details from a model geometry. In the model geometry cleanup example v63.mph, the automatic Geometry Cleanup added Remove Details ... En savoir plus
