This application models a DC glow discharge. The electron energy distribution function (EEDF) and electron transport properties are computed with the Boltzmann Equation, Two-Term Approximation interface. Since input parameters for the Boltzmann Equation, Two-Term Approximation interface, ... En savoir plus
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. En savoir plus
In this example, a hydrogen plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. In the first part of the study, a Maxwellian electron energy distribution function is used. In the second part, the global model is solved self ... En savoir plus
The model illustrate the technique to calculate the magnetic stiffness in a 3D geometry of a permanent magnet axial magnetic bearing. The Magnetic Fields physics is used to model the bearing and compute the magnetic forces. The Deformed Geometry and Sensitivity physics are used to ... En savoir plus
The model of 1D Dielectric Barrier Discharge (DBD) has been recomputed with the three different kinds of electron energy distribution functions (EEDFs): The Maxwellian function The Druyvesteyn function The computed EEDF based on the Boltzmann Equation, Two-Term Approximation ... En savoir plus
This is a primer model of a permanent magnet machine. It is a generic model that can be modified to simulate a motor or generator. It demonstrates different capabilities of COMSOL Multiphysics® to examine aspects of machine design, such as air gap magnetomotive force (MMF), ... En savoir plus
This model is a static 3D simulation of a generator having a rotor with permanent magnets. The center of the rotor consists of annealed medium carbon steel, which is a nonlinear ferromagnetic material that is saturated at high magnetic flux densities. The core is surrounded by several ...

This tutorial shows how the displacement field of a deformed surface can be fit to a Zernike polynomial basis. The method of linear least-squares fitting is made significantly easier when fitting to an orthonormal basis, such as the Zernike polynomials on a circle. The displacement ... En savoir plus
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact so as to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and the rotor being ... En savoir plus
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... En savoir plus
