Isoelectric Separation

This modeling example applies the Transport of Diluted Species interface to model a separation process. A stream containing six different ionic species is divided into pure component streams by means of migrative transport in an electric field. Free flow electrophoresis can be used to separate macromolecules such as proteins, based on their mobility perpendicular to the flow of the carrier fluid. ...

Electrodeposition on a Resistive Patterned Wafer

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated.

Geometric Parameter Optimization of a Tuning Fork

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

Tubular Reactor with Nonisothermal Cooling Jacket

This example uses the Transport of Diluted Species and Heat Transfer in Fluids interfaces as available in the COMSOL Multiphysics base package to study an elementary, exothermic, irreversible reaction in a tubular reactor (liquid phase, laminar flow regime). To keep its temperature down, the reactor also uses a cooling jacket with a nonisothermal coolant temperature. The coolant is modeled with a ...

Piezoelectric Tonpilz Transducer with a Prestressed Bolt

A tonpilz transducer is used for relatively low frequency, high power sound emission. It is one of the popular transducer configurations for SONAR applications. The transducer consists of piezoceramic rings stacked between a head mass and a tail mass which are connected by a central bolt. This example shows how to incorporate the effect of a pre-tension in the bolt. The bolt geometry is imported ...

Pinched Hemispherical Shell

This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations in a case which contains membrane and bending action, as well as large rigid body rotation.

Electrical Heating in a Busbar

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.

Simulating Wireless Power Transfer in Circular Loop Antennas

This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can be easily miniaturized for low frequency applications. While the orientation of a transmitting antenna is ...

Molecular Flow Through an RF Coupler

This model computes the transmission probability through an RF coupler using both the angular coefficient method available in the Free Molecular Flow interface and a Monte Carlo method using the Mathematical Particle Tracing interface. The computed transmission probability determined by the two methods is in excellent agreement with less than a 1% difference. This model requires the Particle ...

Car Windshield Antenna Effect on a Cable Harness

Modern cars have rear-windshield FM antennas to play FM radio. The radiation emitted from an antenna induces an electric current on the outer surface of any cable harnesses in the car, which can have negative effects. This model uses the RF Module to compute the far-field radiation pattern of the antenna, by enclosing the car in perfectly matched layers separated by an air domain. The electric ...
