Flow Past a Cylinder

The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... Читать дальше

Cable Tutorial Series

In this set of eight tutorial models and associated documentation, you can investigate the resistive, capacitive, inductive, and thermal properties of a standard three-core lead-sheathed XLPE HVAC submarine cable with twisted magnetic armor (500 mm2, 220 kV). The series includes a 2D, 2D ... Читать дальше

Frequency Selective Surface, Periodic Complementary Split Ring Resonator

Frequency selective surfaces (FSS) are periodic structures with a bandpass or a bandstop frequency response. This model shows that only signals around the center frequency can pass through the periodic complementary split ring resonator layer. Читать дальше

Chamber Music Hall

In this model, the acoustics of the Small Hall in the Konzerthaus Berlin is simulated with ray tracing. A full study of the room is performed in 1/3-octave bands with 10 pairs of source-receiver positions. The room acoustic parameters are derived from the calculated impulse responses, ...

Laser Heating of a Silicon Wafer

A silicon wafer is heated up by a laser that moves radially in and out over time. In addition, the wafer itself is rotated on its stage. The incident heat flux from the laser is modeled as a spatially distributed heat source on the surface. The transient thermal response of the wafer is ... Читать дальше

Cavity Flow Noise

Flow over a cavity and the tonal noise generated is a typical flow noise source in piping systems that have valves and other cavities. This tutorial model represents a simple case of cavity flow noise in a ducted system. The model is set up based on an example from Lafon et al. The ... Читать дальше

Bracket — Structural Mechanics Tutorials

The bracket models are used as an introduction to structural mechanics modeling with the Structural Mechanics Module. The following features are introduced: The fundamentals: static linear analysis Parametric study Including initial strain Modeling thermal expansion Adding a rigid ... Читать дальше

Stresses and Strains in a Wrench

This tutorial demonstrates how to set up a simple static structural analysis. The analysis is exemplified on a combination wrench during the application of torque on a bolt. Despite its simplicity, and the fact that very few engineers would run a structural analysis before trying to turn ... Читать дальше

Pore-Scale Flow

This non-conventional model of porous media flow utilizes creeping (Stokes) flow in the interstices of a porous media. The model comes from the pore-scale flow experiments conducted by Arturo Keller, Maria Auset, and Sanya Sirivithayapakorn of the University of California, Santa Barbara. ... Читать дальше

Thermo-Structural Effects on a Cavity Filter

This example investigates the electrical performance of a cascaded cavity filter operating in the millimeter-wave 5G band with temperature changes. The thermal variations result in structural deformations of the structure. Thus, the resonant frequencies of the filter elements (cavities) ... Читать дальше
