The Curve Digitizer application can be used to digitize/extract curves from images. This application provides an easy way to digitize a variety of 1D plots with different axes in Cartesian or Polar coordinate system. After a curve image is imported, the digitization is done in a few ... En savoir plus
This example uses the Electric Currents in Layered Shells interface and the Layered Shell interface to model a piezoresistive pressure sensor. The tutorial considers the design of the MPX100 series pressure sensors originally manufactured by Motorola Inc. Although the sensor is no ... En savoir plus
This model presents a method to analyze acoustic damping pads. These pads use a constrained layer of viscoelastic material to dissipate energy and thus reduce the energy radiated as noise. Damping pads are used in many different industries to reduce the noise generated by vibrating ... En savoir plus
This tutorial illustrates how to use built-in variables and operators, for the evaluation of the bulk temperature along a geometry like a channel, a pipe or a chimney, in a nonisothermal flow in 2D and 3D. The bulk temperature may be needed to compute the heat transfer coefficient for an ... En savoir plus
This example exemplifies how to model the switching between current and voltage excitations in Terminal boundary conditions. A more detailed description of the phenomenon and the modeling process can be seen in the blog post "Control Current and Voltage Sources with the AC/DC Module". En savoir plus
This example exemplifies how to model thermal phase change that is subject to hysteresis. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "Thermal Modeling of Phase-Change Materials with Hysteresis" as well as: "How to Use State ...

This benchmark model computes the pressure in a system of outgassing pipes with a high aspect ratio. The results are compared with a 1D simulation and a Monte-Carlo simulation of the same system from the literature. En savoir plus
This example models the desalination of water by capacitive deionization in a "flow-between" cell (fbCDI). The model geometry is in 2D. Steady Brinkman flow, a tertiary current distribution, and the improved modified Donnan description of the deionization process is assumed. En savoir plus
This model computes the input impedance/admittance to an acoustic system in the frequency domain. The system here represents a typical measurement setup used for testing hearing aids and includes domains with thermoviscous boundary layer losses. The input admittance, computed in the ...
