This document explains how to install and run COMSOL Multiphysics® and COMSOL Server™ with Amazon Elastic Compute Cloud™ (EC2™). This requires that you have first acquired a Floating Network License (FNL) or COMSOL Server License (CSL) from COMSOL. The license manager ... En savoir plus
This application uses the shrinking core model to study the reduction of iron ore pellets. A 1D model of a packed bed containing iron ore pellets is modeled. The bed filling pellets initially consists of solid phase FeO. The pellets are reduced by CO, and the solid core shrinks leaving a ... En savoir plus
For models with acoustic-structure couplings it is necessary to calculate the left eigenvectors to use the Frequency Domain, Modal solver. The model shows the necessary changes to the default settings of the eigenfrequency solver. En savoir plus
This model computes an electromagnetic-heated busbar with surface-to-surface radiation and compares the results with the busbar model without radiation. The surface emissivity of copper is varied between 0.1 (blank material), 0.3 (partially oxidized), and 0.7 (heavily oxidized). A more ... En savoir plus
This model demonstrates the use of the Two-Phase Thin-Film Flow, Phase Field multiphysics coupling, which can be used to predict the evolution of an interface between two different, immiscible fluids in thin, narrow channels. The example here presents a free boundary lubrication ... En savoir plus
This case shows how to simulate moisture transport in a homogeneous wall under isothermal conditions. With this assumption, an analytical solution can be calculated. The homogeneous layer is initialized in moisture balance. At the beginning of the simulation, the relative humidity of ... En savoir plus
In this model, a linear magnetic gear system with a gear ratio of 11:4 is modeled. The liner magnetic gear is assumed to be infinitely long with the modular structure that is repeating on either side. Only a single modular section is modeled by using the customized linear periodic ... En savoir plus
Fluence rate is a key parameter for ultraviolet (UV) water purifier. It describes the amount of radiation that pathogens absorb and is then directly related to the disinfection level of the purifier. The aim of this example is to demonstrate the fluence rate calculation with the ... En savoir plus
This model shows how to model a simple Shockley diode— a four-layer PNPN semiconductor device. The Shockley diode is also named as thyristor. In this model, the Analytic Doping Model node is utilized to define the doping profiles for each domain. A time-dependent study is employed to ... En savoir plus
