Flow Past a Cylinder

The following model examines unsteady, incompressible flow past a long cylinder placed in a channel at right angle to the oncoming fluid. The cylinder is offset somewhat from the center of the flow to make the steady-state symmetrical flow unstable. The simulation time necessary for a ... Читать дальше

Laser Heating of a Silicon Wafer

A silicon wafer is heated up by a laser that moves radially in and out over time. In addition, the wafer itself is rotated on its stage. The incident heat flux from the laser is modeled as a spatially distributed heat source on the surface. The transient thermal response of the wafer is ... Читать дальше

Stresses and Strains in a Wrench

This tutorial demonstrates how to set up a simple static structural analysis. The analysis is exemplified on a combination wrench during the application of torque on a bolt. Despite its simplicity, and the fact that very few engineers would run a structural analysis before trying to turn ... Читать дальше

Bracket — Structural Mechanics Tutorials

The bracket models are used as an introduction to structural mechanics modeling with the Structural Mechanics Module. The following features are introduced: * The fundamentals: static linear analysis * Parametric study * Including initial strain * Modeling thermal expansion * Adding a ... Читать дальше

Heat Transfer by Free Convection

This example describes an array of heating tubes submerged in a vessel with fluid flow entering at the bottom. This is a multiphysics model because it involves fluid dynamics coupled with heat transfer. The pressure and the velocity field are the solution of the Navier-Stokes equations, ... Читать дальше

Magnetic Gear in 2D

This model presents the transient modeling of a coaxial magnetic bearing using permanent magnets. The coaxial magnetic bearing is advantageous over the conventional mechanical gear mainly because of minimum noise, maintenance free operation, overload protection and physical isolation ...

Permanent Magnet

As an example of a magnetostatic problem, consider how to model a horseshoe-shaped permanent magnet. One way is to treat the entire magnet as a ferromagnetic material, where the two end sections are defined as being pre-magnetized in different and opposite directions. Читать дальше

Fluid-Structure Interaction

This model demonstrates how to set up a fluid-structure interaction problem in COMSOL Multiphysics. It illustrates how fluid flow can deform solid structures and how to solve for the flow in a continuously deforming geometry. The Fluid-Structure Interaction (FSI) multiphysics interface ...

E-Core Transformer

This is the transient model of a single phase E-core transformer using a Multi-Turn Coil Domain. The model includes the effect of a nonlinear B-H curve in the core and shows how to connect the transformer model to the external circuits using Electric Circuit interface. The simulation is ...

Evaporation in Porous Media with Large Evaporation Rates

Evaporation in porous media is an important process in the food and paper industries, among others. Many physical effects must be considered: fluid flow, heat transfer, and transport of participating fluids and gases. All of these effects are strongly coupled and predefined interfaces ...
