When a droplet is placed on a substrate on which surface acoustic waves (SAWs) are traveling, the energy of the SAWs is transferred into the droplet to form an acoustic field. The transferred energy is attenuated and generates a streaming flow. This type of streaming enables contactless ... Mehr lesen
This model compares the results of five different formulations and approaches to solving an RF heating problem consisting of a coaxial cable inserted into a sample of lossy dielectric material. Results show that the different formulations agree over a wide frequency band. To learn more ... Mehr lesen
This example demonstrates how to compute transmission line parameters such as series resistance, series inductance, shunt conductance, and shunt capacitance per unit length using the predefined Transmission Line RLGC Parameters multiphysics interface. The demonstration also includes the ... Mehr lesen
In this tutorial, a filter system for a diesel engine is modeled, including a soot layer development and oxidization. The build-up of the layer is held in check by both catalytic and non-catalytic reactions, where carbon is oxidized to carbon monoxide and carbon dioxide, which in turn ... Mehr lesen
In this tutorial, an uncertainty quantification analysis is performed on the Microstrip Patch Antenna model from the RF Module Application Library to explore how variations in input parameters, such as material properties or geometric variations, impact the antenna’s performance in terms ...

Example for a geometry sequence to deduce a shell model from an imported solid CAD file. The model demonstrates how to generate parameters from dimensions of a geometry and how to convert a solid CAD geometry into a shell representation using midsurface and extract Mehr lesen
This example shows how to model a FinFET in 3D. The I-V characteristics of the device are simulated. First, the gate voltage is swept to obtain the drain current versus gate voltage plot. Then, the drain current versus drain voltage characteristics are computed for fixed gate voltages. Mehr lesen
This example simulates the propagation of a positive streamer in transformer oil under a lightning impulse voltage. The space charge density and the electric field are obtained. The simulated streamer radius agrees well with the measured values. Mehr lesen
This model demonstrates the use of optical tracing for studying optically large gradient-index structures with anisotropic optical properties. Additionally, the model introduces a smoothing technique for handling discontinuities of refractive index on curved surfaces, which are typical ... Mehr lesen
Kinetic analysis of catalytic reactions is essential for understanding rate behavior as well as the reaction mechanism. Developing knowledge of intrinsic reaction kinetics and of rate equations is central to reaction engineering studies aimed at improving reactor design. This model ... Mehr lesen
