Acoustics of Coupled Rooms Using the Acoustic Diffusion Equation
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
Rowland Circle Spectrometer
The Rowland circle is a circle of radius R that lies tangent to a concave curved diffraction grating of radius 2R. If the entrance slit of incoming light is positioned on this circle, then rays reflected by the grating will be focused at various points along the same circle based on ... 詳細を見る
Turbulent Parallel Flow in a Channel with Adjacent Fluid and Porous Regions
This setup demonstrates how the characteristics of turbulent flow in a channel are modified by the presence of an adjacent porous region. Asymmetric velocity profiles, higher turbulence levels, and higher friction coefficients both at the solid wall and the fluid-porous interface are ... 詳細を見る
LIDAR : Light detection and ranging using Ray optics module
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... 詳細を見る
Image to Curve Add-In Examples
These example models demonstrate using the Image to Curve add-in, which is included in COMSOL Multiphysics® version 5.5. One example shows a simple structural analysis. An image of an H-beam is imported to a work plane and then extruded. A distributed load is applied to the beam ... 詳細を見る
Stray Currents from a Train in a Light Railway Transit System
Light railway transit (LRT) systems often utilize DC power for train propulsion. In these systems the potential gradients in the rails may induce stray currents, which corrode nearby metallic structures. In this example the Cathodic Protection interface, using Edge Electrode nodes, is ... 詳細を見る
Thermal Insulation on Internal Boundary
The purpose of this model is to introduce the Thermal Insulation feature available in Heat Transfer interfaces. Thermal Insulation is the default feature for external boundaries. An additional Thermal Insulation node is necessary in order to apply a thermal insulation condition to an ... 詳細を見る
Dynamics of a Roller Chain Sprocket Assembly
Chain drives are used for transmitting power from one shaft to another, located at some distance. This example simulates the dynamics of a chain sprocket assembly in 2D. The geometry consists of a roller chain wrapped around two sprockets. Both chain links and sprockets are assumed to be ... 詳細を見る
Damping Coefficients of a Squeeze Film Damper
Squeeze film dampers are components that provide additional damping to rotating machines. To simplify the modeling of a rotor assembly, squeeze film dampers are modeled in terms of their damping coefficients which are a functions of the journal location in the damper. This model computes ... 詳細を見る
Topology Verification for Surface-to-Surface Radiation
These tutorial models show how to use the tools to assist with defining surface-to-surface radiation models. In the first model, radiation direction symbols are used to find an unexpected configuration where the opacity is not correctly defined. In the other, the topology check ... 詳細を見る
