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
You can use the Moving Mesh or the Deformed Geometry interface to implement wrapping of a CAD part around one axis. This model demonstrates both how to implement this wrapping, as well as how to subsequently mesh the surrounding volume around the deformed part. A more detailed ... En savoir plus
This example exemplifies how to model the Beer-Lambert law using the core functionality of COMSOL Multiphysics. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Modeling Laser-Material Interactions with the Beer-Lambert Law". En savoir plus
Gradient-based optimization is an efficient way of computing better values for many control variables. This example optimizes diameters of individual members in a truss structure such that the structure becomes stiffer without adding mass to the structure. The structure will be only be ...

This model demonstrates the effect of the hopper design on the resulting flow patterns of the grains exiting the hopper. The flow changes from mass flow to funnel flow when the conical angle of the hopper is increased. En savoir plus
In this model of a single-beam optical trap, SiO2 nanospheres in streaming water pass by or get captured depending on where they are released from. The electromagnetic force on the particles is calculated in the Electromagnetic Waves, Frequency Domain interface, with a Gaussian ... En savoir plus
This example demonstrates an app that utilizes the LiveLink™ interface for Inventor® to run simulations on CAD designs. En savoir plus
This tutorial shows how to simulate coupled heat and moisture transport in a wall. The wall is modeled considering an air flow between interior and exterior varying with time. The 1D model is the third benchmark test defined in HAMSTAD-WP2 Modeling for the validation of numerical ... En savoir plus
Carbon corrosion is one of the important degradation mechanisms in a Polymer Electrolyte Membrane (PEM) fuel cells which predominantly occurs during start-up or shut down of the fuel cells. During carbon corrosion, carbon support to catalysts is compromised affecting the cell ... En savoir plus
Pitting corrosion is localized corrosion by which local cavities, pits, are formed on a seemingly initially smooth metal surface. A pit may be initiated due to small surface defects, such as inhomogeneities in composition or shape, or from mechanical abuse. How and if the pit grows ... En savoir plus
