磁場中の鉄球は, 磁場が透過性材料と相互作用する効果を示す優れた教科書的な例です. このチュートリアルシリーズは, COMSOL を用いた電磁効果の数値モデリングの入門として設計されています. このシリーズでは, 静的背景磁場と 60 Hz, 20 kHz, 13.56 MHz の3つの時間変動磁場からなる4つの異なる背景磁場レジームを解析します. これらのレジームはそれぞれ独自の挙動と前提を持ち, 異なるモデリング手法を用いています. これらのモデルはすべて, 入門モデルを出発点として, 任意の順序で完成させることができます. 詳細を見る

This model presents a time-dependent study of a microchannel that is used to infuse and flush another piece of equipment with a fluid. The pressure at the five inlets varies sinusoidally as functions of time, and the velocity vector at the outlet is studied. The model uses an ... 詳細を見る

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 ... 詳細を見る

The small strain overlay material model captures the effect of high stiffness at low strain as well as the hysteresis under cyclic loading, which is a common effect for most soils. The formulation allows stiffness degradation with an increase in shear strain, and the full recovery of ... 詳細を見る

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 ... 詳細を見る

A simple equivalent circuit model approach is presented for Nickel metal hydride batteries. The 0D model consists of resistor, capacitor, current source and state-of-charge based voltage source (SOC). An Arrhenius type dependence is used to account for self-discharge. All model ... 詳細を見る

Just like optical lenses focus light, electric and magnetic lenses can focus beams of charged particles. Systems of magnetic quadrupole lenses find a common use in focusing both ion and particle beams in accelerators at nuclear and particle physics centers. This model shows the path of ... 詳細を見る
