This app allows to calculate the absorption coefficient and surface impedance of a sound absorbers for normal and random incidences. The computed quantities can be used when setting up boundary conditions in a Pressure Acoustics, Frequency Domain model or a Ray Acoustics model. The ... 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

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 demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in ... 詳細を見る

This model exemplifies the use of the Rotating Machinery interface, which allows you to model moving rotating parts in, for example, stirred tanks, mixers, and pumps. The Rotating Machinery interface formulates the Navier-Stokes equations in a rotating coordinate system. Parts that are ... 詳細を見る

Thermoelastic damping, which arises when you subject a material to cyclic stress, is an important factor when designing MEMS resonators. The stress brings about deformation, where materials heat under compressive stress and cool under tensile stress. Thus, due to the resulting heat flux, ... 詳細を見る

This model illustrates how to compute the torque of a three-phase squirrel-cage induction motor at various speeds. In the example the torque is computed by averaging the results from simulations performed on 2D cross sections at several locations along the induction motor. The 3D ... 詳細を見る

This benchmark model computes the load-carrying capacity of a one dimensional hydrodynamic step bearing. The results are compared with analytic expressions obtained by solving the Reynolds equations directly in this simple case. 詳細を見る

This example shows how to estimate the permeability of a porous material by creating a detailed fluid flow model in a small unit cell. The result of the model is a lumped permeability of the material, which can be used in homogenized models using Darcy's law or the Brinkman equations. ... 詳細を見る

The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. In this case, the flow is subjected to a sudden increase of cross-sectional area, resulting in a separation of flow starting at the point of expansion. Spatial ... 詳細を見る
