This verification model analyzes the acoustics of two coupled rooms using the Acoustic Diffusion Equation interface of the Acoustics Module. The results of the model agree with numerical results that are validated against measurements in a reference paper. 詳細を見る

The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... 詳細を見る

Thermoelectric elements are often used to cool or heat electronic components to a desired temperature. In such simulations, you are typically not interested in the behavior of the thermoelectric element itself but want to use its performance characteristics to model the overall response ... 詳細を見る

Finding acoustic eigenmodes in problems solved with linearized convected acoustic interfaces can be a challenging task. The solution will most often return several non-acoustic vorticity and entropy modes. These are highly damped waves that do not propagate at the speed of sound but with ... 詳細を見る

Underground train grids span large areas under London, Paris, New York, and other cities. The building regulations require strict noise standards, and failure to comply could result in significant losses in the market prices of developments. Therefore, train-induced noise has to be ... 詳細を見る

This tutorial model shows a system consisting of a Helmholtz resonator on the side of a main duct. The resonator volume is partly filled with a porous material. The model computes the reflection, transmission, and absorption of the system. Thermoviscous losses are included in the model ... 詳細を見る

This models pressure-dependent heating of 4 inch wafer on unipolar electrostatic chuck. Wafer sits on top of ring with electrostatic force holdong down wafer to counter upward pressure from gas flowing in gap between wafer and chuck surface. It is a problem involving 4 coupled physics ... 詳細を見る

このチュートリアルでは, 単純な静的構造解析を設定する方法を説明します. 解析は, ボルトにトルクをかける際のコンビネーションレンチを例にしています. その単純さと, ボルトを回す前に構造解析を実行するエンジニアはほとんどいないという事実にもかかわらず, この例は COMSOL Multiphysics における構造解析の優れた例を示しています. 詳細を見る

This is a full vibro-electroacoustic simulation of a balanced armature transducer (BAT or also known as a receiver in some industries) which is a high-performance miniature loudspeaker often used in hearing aids and other in-ear audio products such as earbuds. The model is set up and ... 詳細を見る

This model describes the evaporation of a droplet that consists of concentrated solution of acetone and water. It accounts for the coupled phenomena of chemical species transport and heat transfer over phase boundaries (liquid-gas boundary) as well as for multiphase flow. The droplet ... 詳細を見る
