Gate Valve in Pipe Branch

A gate valve in a piping branch point is simulated using high viscosity in the gate itself. A parametric run varies gate position from 100% open to fully closed

Electric Heating in a Busbar, Modeled with LiveLink for Inventor - new

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Inventor and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.

An Electrokinetic Valve in a Microchannel System

This model presents an example of pressure driven flow and electrophoresis in a microchannel system. The modeled device is often used as an electrokinetic sample injector in biochips with well-defined sample volumes of dissociated acids and salts. The model presents a study of a pinched injection cross valve during the focusing, injection, and separation stages. Focusing is obtained through ...

Modeling a Distributed Model of Thermal Microactuator on a Cluster - new

A model of a thermal microactuator requires the coupled simulation of electric current conduction with heat generation, heat conduction, and structural stresses and strains due to thermal expansion. The purpose of this model is to demonstrate how to access the cluster computing functionality in COMSOL from COMSOL Desktop and use it to submit a batch job to a cluster through a job scheduler. The ...

Lombardi Surface Mobility in a Semiconductor - new

Surface acoustic phonons and surface roughness have an important effect on the carrier mobility, especially in the thin inversion layer under the gate in MOSFETs. The Lombardi surface mobility model adds surface scattering resulting from these effects to an existing mobility model using Matthiessen’s rule. This model demonstrates how to use the Lombardi surface mobility model for the electron ...

Tapered Membrane End Load - new

This example shows a 2D plane stress model of a membrane with a thickness of 0.1 m. The load is a uniformly distributed horizontal load of 10 MN/m (that is, a pressure of 100 MPa) along the right end. At the left end, the membrane is constrained from movement in the x direction. At the left end's midpoint, the membrane is kept fixed. The resulting x-direction stress is compared to a NAFEMS ...

Stationary Incompressible Flow over a Backstep using Argyris Elements

This model examines the physics of plane, incompressible and steady flow over a backward step in the absence of external forces. It addresses a common benchmark problem in the field of computational fluid dynamics. There is no known exact solution, but experimental data have been published, making it possible to check the accuracy of the FEM solution. The model exemplifies a divergence-free ...

Lumped Receiver Connected to Test Set-up with an 0.4-cc Coupler - new

In this model a Knowles ED23146 receiver (miniature loudspeaker) is connected to a test set-up consisting of a 50 mm (1 mm diameter) earmold tube and a so-called 0.4-cc coupler. The receiver is modeled using a lumped spice network and connected to the finite element domain at the tube inlet. The response at the measurement microphone in the coupler as well as the electric input impedance to the ...

Optimization of a Tuning Fork, Modeled with LiveLink for Inventor - new

This model computes the fundamental eigenfrequency and eigenmode for a tuning fork that is synchronized from Inventor via the LiveLink interface. The length of the fork is then optimized so that the tuning fork sounds the note A, 440 Hz.

Electric Heating in a Busbar, Modeled with LiveLink for Solid Edge - new

This tutorial model of the Joule heating effect in a busbar demonstrates how to synchronize an assembly between Solid Edge and COMSOL, how to modify the geometry from COMSOL, and how to run a geometric parametric sweep.
