Parameterized Window Preset Model

During the design of a building, environmental issues have gained considerable influence in the entire project. One of the first concerns is to improve thermal performances. In this process, simulation software are key tools to model thermal losses and performances in the building. The international standard ISO 10077-2:2012 deals with thermal performance of windows, doors and shutters. It ...

TM Mode Microwave Plasma

This model shows how to simulate a TM mode microwave plasma by using the Doppler broadening parameter to smooth out the resonance zone, which occurs on the contour of critical electron density. A detailed explanation of the underlying physics of this model can be found in the blog entry "Application Note on Microwave Discharges".

Simulation of an Electromagnetic Sounding Method for Oil Prospecting

The marine controlled source electromagnetics method (CSEM) for oil prospecting has emerged as a promising technique during recent years. This model demonstrates one variant of it. It uses a mobile horizontal 1 Hz electric dipole antenna that is towed 150 m above the sea floor. An array of sea floor receivers measure the electric field at various distances away from the antenna. When measuring ...

Ion Range Benchmark

The Ion Range Benchmark model simulates the passage of energetic protons through silicon with both ionization losses and nuclear scattering. The initial energy of the protons is varied using a parametric sweep from 1 keV to 100 MeV. The average path length of the protons is compared to published values of the ion range under the continuous slowing down approximation (CSDA) as well as the ...

DC Characteristics of a MESFET

In a MESFET, the gate forms a rectifying junction that controls the opening of the channel by varying the depletion width of the junction. In this model we simulate the response of a n-doped GaAs MESFET to different drain and gate voltages. For a n-doped material the electron concentration is expected to be orders of magnitude larger than the hole concentration. Accordingly, it is possible to ...

Stefan Tube

This example illustrates the use of the Maxwell-Stefan diffusion model available with the Transport of Concentrated Species interface. It models multicomponent gas-phase diffusion in a Stefan tube in 1D. In this case, it is a liquid mixture of acetone and methanol that evaporates into air. The concentration profiles are modeled at steady-state and validated against experimental data by Taylor ...

Frame Fatigue Life

Analyzing fatigue with simulation, rather than running fatigue experiments, is a much quicker way to determine whether a certain design will fail after repeated loading and unloading. This application allows you to evaluate the fatigue life of a frame with a cutout. It is useful for understanding the concept of fatigue and how to build an equivalent app for your own designs. The Frame Fatigue ...

Equivalent Properties of Periodic Microstructures

Periodic microstructures are frequently found in composite materials, such as carbon fibers and honeycomb structures. They can be represented by a unit cell repeated along three directions of propagation. To reduce computational costs, simulations may replace all of the microscopic details of a composite material with a homogeneous domain with equivalent properties. This app computes the ...

Si Solar Cell with Ray Optics

The Si Solar Cell with Ray Optics app combines the Ray Optics Module and the Semiconductor Module to illustrate the operation of a silicon solar cell for a specific date and location. The Ray Optics Module computes the average illumination for a date and location that are chosen by the app's user. Then, the Semiconductor Module computes the normalized output characteristics of the solar cell ...

Tilted Pad Thrust Bearing

Tilted pad thrust bearings are used in rotating machineries with high thrust loading. The thrust load is transferred from a sliding part to a stationary part through hydrodynamic oil films. The tilted pad thrust bearing consists of a series of flat surfaces sliding over stationary tilted pads. The space between the flat surface and the tilted pad is filled by a lubricant that is drawn in due to ...
