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 file shows how to create a surface of an irregular shape based on text, image, or elevation data. This approach is best suited for data where the height (or elevation) is a function of x- and y-coordinates. The data is of the Matterhorn, a European mountain located in the Alps. In ...

This model demonstrates three different ways to find the eigenfrequencies of a rectangular metallic cavity. The first method uses an eigenfrequency study step together with the Electromagnetic Waves, Beam Envelopes interface. Here, it is important to define a wave vector for the physics ... En savoir plus
This tutorial studies the propagation of sound in the presence of a porous absorber in the time domain. It demonstrates how to model a porous absorber using the local and extended reacting approximations and compares the two approaches for absorbers of various thickness. The dissipative ...

A classic way of estimating pi is by using the Monte Carlo method. This involves randomly placing points inside a square and counting how many lie within a circle inscribed in the square. The ratio of points inside the circle to the number of points in total can be used to approximate ... 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
The purpose of this model is to introduce the specular reflection in Surface-to-Surface Radiation using the ray-shooting algorithm. Different parameters are available to the user to yield better accuracy in the results when using the ray-shooting algorithm. The model is a standard ... 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
