Motion of Trapped Protons in Earth's Magnetic Field

This model demonstrates the path of non-relativistic protons within Earth's magnetic field. Due to the dipole nature of Earth's magnetic field, charged particles, such as electrons and protons, can get trapped in stable configurations within it for long periods of time. These configurations involve the particles rapidly bouncing from magnetic pole to magnetic pole, and drifting around the ...

Jet Pipe

This example models the radiation of fan noise from the annular duct of a turbofan aeroengine. When the jet stream exits the duct, a vortex sheet appears along the extension of the duct wall due to the surrounding air moving at a lower speed. The near field on both sides of the vortex sheet is calculated. The linearized Potential Flow physics interface in the Acoustics Module describes acoustic ...

Rotating Galaxy

This tutorial model shows how to add customized particle-particle interaction forces. In this example the gravitational force between 2500 stars in a galaxy is modeled. The galaxy initially rotates as a rigid body, then begins to change shape due to gravitational forces.

Behavior of Power Law Fluids in a Mixer

This model shows how to use simulations to predict power numbers with Power Law fluids in a mixer. It simulates the behavior of flow in a flat bottom tank with a single four-blade pitched impeller. The flow was modeled as laminar and the frozen rotor approach was used to solve the discrete governing equations in one quarter of a baffled tank. The calculated power numbers were compared with ...

Kirsch Infinite Plate Problem

This model describes a static stress analysis to obtain the stress distribution in the vicinity of a small hole in an infinite plate. The model is a classic benchmark and is described in Mechanics of Material, by D. Roylance. The stress level is then compared with the theoretical values.

Slip Flow Benchmark

This model is a benchmark model for the Slip Flow interface. It is based on both analytic and numeric calculations. Air at atmospheric pressure flows through a conducting micro-channel connecting two reservoirs maintained at different temperatures. A flow between the two reservoirs develops as a result of thermal creep along the channel wall, which in turn produces a pressure gradient. At steady ...

Microphone grid free-field level correction curve for plane-wave incidence

This is a conceptual model of a microphone placed in an infinite baffle (flush mounted). The purpose is to determine the free-field level correction curve of the setup, which includes the exterior domain, microphone grid, and volume between the grid and the diaphragm. The microphone diaphragm is characterized with a simple RCL impedance and the open radiation condition is modeled with a ...

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 ...

Electrodeposition of a Microconnector Bump with Deforming Geometry in 3D

This model simulates the shape evolution of a microconnector bump over time as copper deposits on an electrode surface. Transport of cupric ions in the electrolyte occurs by convection and diffusion. The electrode kinetics are described by a concentration dependent Butler-Volmer expression. The model is an extension to 3D of the Electrodeposition of a Microconnector Bump in 2D example.

Mixed Diffuse-Specular Radiation Benchmark

This model shows how to use the Mathematical Particle Tracing interface to simulate mixed diffuse-specular reflection between surfaces in an enclosure. This model is separated in two parts. The first part compares the heat fluxes computed by the Mathematical Particle Tracing interface with the exact solution for two identical infinitely long parallel grey plates under mixed diffuse-specular ...
