This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... En savoir plus
These examples demonstrate how to generate randomized geometric surfaces. Note that there is now also an add-in covering random surface functionality for planar surfaces. The COMSOL Multiphysics® software provides a powerful set of built-in functions and operators, such as ... En savoir plus
Unwanted arcing can have serious adverse effects on electrical and electronic equipment and systems. To improve the understanding and prediction of arc dynamics, it is crucial to conduct multiphysics simulations of transient arc processes. This model features a 3D simulation of transient ...

This model demonstrates how to simulate the propagation of guided waves in a dielectric S-bent optical waveguide. The model demonstrates that the phase approximation, required by the Electromagnetic Waves, Beam Envelopes interface, can be numerically calculated by solving an additional ... En savoir plus
In this example water ponded in a ring on the ground moves into a relatively dry soil column and carries a chemical with it. As it moves through the variably saturated soil column, the chemical attaches to solid particles, slowing the solute transport relative to the water. Additionally ... En savoir plus
In this example, a simplified micromechanical model of a unit cell with periodic boundary conditions is analyzed. The homogenized elastic and thermal properties of a composite material are computed based on individual properties of fiber and matrix. A comparison of numerical values are ... En savoir plus
The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. In this example, the formation period of an Argon plasma is studied with special attention paid to the EEDF. The plasma is created within a 4 cm gap by a DC source voltage of 1 ... En savoir plus
This model simulates electrical breakdown in an atmospheric pressure gas. Modeling dielectric barrier discharges in more than one dimension is possible, but the results can be difficult to interpret because of the amount of competing physics in the problem. In this simple model the ... En savoir plus
Capacitively coupled RF discharges can operate in two distinct regimes depending on the discharge power. In the low power regime, known as the alpha regime, the electric field oscillation is responsible to heat and create electrons. In the high power regime, known as gamma regime, the ... En savoir plus
Powder compaction is a popular manufacturing process not only in powder metallurgy, but also in the pharmaceutical industry. The Capped Drucker–Prager model is commonly used for simulating the compaction processes of pharmaceutical powders, where the material properties depend on the ... En savoir plus
