Laser Cavity with a Thin Lens
In this model, two flat end mirrors are placed at a distance and a spherical lens is inserted in the middle of the cavity. A ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the ... Mehr lesen
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 ... Mehr lesen
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. Mehr lesen
Curve Digitizer
The Curve Digitizer application can be used to digitize/extract curves from images. This application provides an easy way to digitize a variety of 1D plots with different axes in Cartesian or Polar coordinate system. After a curve image is imported, the digitization is done in a few ... Mehr lesen
Competing Reactions
Tutorial model investigating a set of two competing reactions. The model demonstrates the natural modeling strategy for reaction engineering in COMSOL Multiphysics®. That is, how to go from chemical equations to space-dependent models of reacting flow with a minimum of work. Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
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 ... Mehr lesen
Density-Gradient and Schrödinger–Poisson Results for a Silicon Inversion Layer
This tutorial demonstrates the use of the density-gradient formulation to include the effect of quantum confinement in the device physics simulation of a silicon inversion layer. This formulation requires only a moderate increase of computational resources as compared to the conventional ... Mehr lesen
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 ... Mehr lesen
