Many robot vacuum cleaners nowadays are equipped with lidar for spatial mapping in order to design an optimal cleaning path and navigate in a room without bumping into obstacles. This model simulates the lidar of a robot vacuum cleaner and how it maps out the shape of the room using ... 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 ...

This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... 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 model describes a pencil beam scanning (PBS) magnet system for use in medical proton therapy. Simulations of the magnetic flux density and particle tracing are performed. Such models are useful for the design of PBS systems, particular with the advent of MR-integrated proton ... En savoir plus
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... En savoir plus
This model demonstrates how to find the optimal size and position of a water pipe in an air chamber, so that the energy absorption in the water is maximized. The objective is implemented as a constraint, so that the optimization terminates, when the desired performance is achieved. En savoir plus
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... En savoir plus
This example exemplifies how to model the impedance of a waveguide of varying cross sectional area. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Computing the Impedance of a Corrugated Waveguide". En savoir plus
This proof-of-concept model showcases how to handle a Gaussian beam propagating in the negative y direction in 2D. The model includes several studies, including a parametric sweep, to cover a wide combination of settings describing the background Gaussian beam, such as settings for ... En savoir plus
