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
During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The ... En savoir plus
Zinc-Silver oxide (Zn-AgO) batteries are used in different industries due to their high capacity per unit weight. In this work, discharge of a Zn-AgO battery is simulated using the Battery with Binary Electrolyte interface. The electrochemical reactions in the positive and negative ... En savoir plus
In this example, the deformation of a rubber boot seal connected to a rigid pipe is studied. As the pipe rotates and the seal deforms, the flanges of the seal self-intersect and it also come into contact with the pipe. En savoir plus
Mixed-mode S-parameters describe the responses of a circuit with balanced ports excited and terminated by two types of modes: common and differential modes. They are calculated using a full S-parameter matrix of a four-port network that is composed of four single ended lines. This ... En savoir plus
This tutorial model demonstrates how to set up a parameter estimation study for fitting the material parameters of an Ogden hyperelastic model to experimental data. The procedure considers multiple load cases under large deformations, which is often necessary to obtain constitutive ... En savoir plus
The sound distribution from a TV in a two-room apartment is computed. The simulation demonstrates the use of the Acoustic Diffusion Equation interface to get a quick and simple estimate of the local sound pressure level. For increased accuracy, an analytical expression for the direct ... En savoir plus
This example shows how to perform parameter optimization on a lens system. The optimization is motivated by the replacement of one of the glasses in a prior optical prescription with a new glass having slightly different optical dispersion coefficients. The control parameters are the ... En savoir plus
Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is ... En savoir plus
This app allows to calculate the absorption coefficient and surface impedance of a sound absorbers for normal and random incidences. The computed quantities can be used when setting up boundary conditions in a Pressure Acoustics, Frequency Domain model or a Ray Acoustics model. The ... En savoir plus
