This example simulates an oil droplet rising through a suspension. The suspension is initially stratified, with a dense layer between two clear layers. The droplet is initially located in the bottom clear layer. The particles in the suspension start to sediment toward the bottom of the ... Mehr lesen
This model analyzes a piezoelectric microelectromechanical system (MEMS) speaker. The speaker, composed of four triangular membranes, uses a layer of lead zirconate titanate (PZT) material with two electrodes on top of a silicon layer as actuators. The triangular membranes are separated ... Mehr lesen
This is a simple yet powerful simulation app for designing a two-dimensional reflective metalens. This metalens consists of a array of glass nanopillars on a metal substrate. Initially, the app determines the optimal grating parameters for a specific wavelength and calculates the ... Mehr lesen
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... Mehr lesen
This tutorial model demonstrates how to estimate the material parameters of a viscoplastic Bergstrom–Boyce model suitable for nonequilibrium modeling of rubber-like materials. The data used for parameter estimation consists of cyclic uniaxial tension and compression tests at two ... Mehr lesen
In this example, the mechanical impact of a golf club hitting a golf ball is studied. The contact between the two parts is modeled using a viscous penalty formulation to stabilize the dynamic event. To properly model the large deformation, the golf ball is defined using a hyperelastic ... Mehr lesen
During quenching of steel, austenite decomposes into phases such as ferrite, pearlite, bainite, and martensite. A common way to illustrate the phase transformation characteristics of a particular steel alloy is to use transformation diagrams. Two of the most commonly used diagram types ... Mehr lesen
This model simulates the propagation of a double-headed streamer in nitrogen at atmospheric pressure. Initially, electron-positive ion clusters were introduced between two parallel electrodes, subjecting the gas to a strong background electric field of 52 kV/cm. Subsequently, both the ... Mehr lesen
This model is a benchmark for three-phase flow commonly used in food processing, pharmaceutical industry, and chemical processing. The results are validated against data reported in the literature. A gas bubble rises through two layers of liquid, a lighter liquid resting on top of a ... Mehr lesen
Topology optimization for low volume fractions in 3D follows the same methodology as in 2D for medium volume fractions. The only difference is the need for iterative solvers. This model demonstrates topology optimization of a drone for a volume fraction of 12.5 %, while considering two ... Mehr lesen
