This tutorial shows how the displacement field of a deformed surface can be fit to a Zernike polynomial basis. The method of linear least-squares fitting is made significantly easier when fitting to an orthonormal basis, such as the Zernike polynomials on a circle. The displacement ... 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
This model demonstrates how to couple the Radiative Beam in Absorbing Media interface to the Radiation in Absorbing-Scattering Media interface. To learn more about this model, see our accompanying blog post “Modeling Absorption and Scattering of Collimated Light”. 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 model demonstrates continuous magnetophoretic separation of particles in a 3D microfluidic Y-channel using a permanent magnet. Separation is achieved through the balance between the magnetophoretic force and hydrodynamic drag. En savoir plus
This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. En savoir plus
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ...

Formally known as size separation in vibrated granular materials, the Brazil nut effect (BNE) (and sometimes the Muesli effect) is a phenomenon that causes large grains to separate from small ones and rise to the top of a granular bed under vibrations. This phenomenon can be studied ... En savoir plus
This application generates both random and deterministic microstructures from imported CAD models or predefined primitive objects. Structures can be created using Gaussian random fields, random particles, periodic geometries such as gyroids and other TPMS structures, or combinations ... En savoir plus
