A hinge between two mechanical components is modeled by coupling two rigid connectors. This method can be used for simulating many types of mechanisms. In mechanical assemblies, parts are sometimes connected so that they are free to move relative to each other in one or more degrees of ... En savoir plus
A diplexer is a device that combines or splits signals into two different frequency bands, widely used in mobile communication systems. This model simulates splitting properties using a simplified 2D geometry. The computed S-parameters and electric fields at the lower and upper bands ... En savoir plus
A circular waveguide filter is designed using a 2D axisymmetric model. Six annular rings added to the waveguide form circular cavities connected in series, and each cavity cutoff frequency is close to the center frequency of the filter. The simulated S-parameters show a bandpass ... En savoir plus
Induced eddy currents and associated thermal loads is of interest in many high power AC applications. This example is of general nature and illustrates some of the involved physics as well as suitable modeling techniques in the AC/DC Module. In this model a metallic plate is placed ... En savoir plus
An established method for benchmarking the atmospheric corrosion resistance of materials is the use of accelerated corrosion tests (ACT) performed in climate chambers. The main purpose of the ACTs is to make reliable and fast predictions of the long time behavior. The tests expose ... En savoir plus
This tutorial simulates a standard test and benchmark model for perfectly matched layers (PMLs) as absorbing boundary conditions in the time domain. It involves the propagation of a transient Gaussian pulse with no flow. The Pressure Acoustics, Transient interface is used together with ... En savoir plus
This tutorial uses a 2D model of an acoustically driven microfluidic pump. The acoustic microfluidic pump is driven by acoustic streaming originating from sharp edges in the microfluidic channel. It drives a flow around a closed microfluidic channel loop. The acoustic field is modeled ... En savoir plus
This model describes the pressure wave propagation in a muffler for an internal combustion engine. The purpose of the model is to show how to analyze both inductive and resistive damping in pressure acoustics as well as coupling the fluid to the surrounding elastic shell structure of the ...

This app simulates sedimentation of particles or agglomerations of particles in a solution. The distribution of particles or agglomerations of particles is taken into account. En savoir plus
The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the ... En savoir plus
