Galeria de Modelos

The Model Gallery features COMSOL Multiphysics model files from a wide variety of application areas including the electrical, mechanical, fluid, and chemical disciplines. You can download ready-to-use models and step-by-step instructions for building the model, and use these as a starting point for your own modeling work. Use the Quick Search to find models relevant to your area of expertise, and login or create a COMSOL Access account that is associated with a valid COMSOL license to download the model files.

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

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.

Elastoplastic Analysis of Holed Plate

A plate modeled using the Plane Stress interface is loaded above the elastic limit. The material is elastoplastic with isotropic hardening. The plot shows the plastic zone.

Fine Chemical Production in a Plate Reactor

Plate reactors running under continuous conditions have emerged as candidates to replace batch reactors, primarily in fine chemicals and pharmaceuticals production. One of the advantages of the plate reactor design is that it allows for efficient temperature control of the reacting fluid. For instance, this means that the heat released from strongly exothermic reactions can be readily dissipated ...

Argon Boltzmann Analysis

The electron energy distribution function (EEDF) plays an important role in the overall behavior of discharges. Analytic forms of the EEDF exist such as Maxwellian or Druyvesteyn, but in some cases they fail to fit the discharge physics. This tutorial model investigates the effects of various parameters on the electron energy distribution function and rate coefficients for an argon discharge. ...

Oxygen Boltzmann Analysis

The Boltzmann equation can be solved to validate sets of electron impact collision cross sections. In fact, sets of collision cross sections are traditionally inferred by solving a two-term approximation to the Boltzmann equation and comparing the results to swarm experiments. This model solves a two-term approximation to the Boltzmann equation and compares the computed drift velocity and ...

GEC CCP Reactor, Argon Chemistry, 1D

The NIST GEC CCP reactor provides a platform for studying capacitively coupled plasmas. Even the simplest plasma models are quite involved so a 1D example helps in understanding the physics without excessive CPU time. The problem has no steady-state solution, although a periodic steady-state solution is reached after a suitable number of RF cycles (usually >1000).

Pacemaker Electrode, Modeled with LiveLink for Pro/ENGINEER

This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in Pro/ENGINEER by using the LiveLink interface.

Electric Heating in a Busbar, Modeled with LiveLink for SolidWorks

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

Geoelectrics - Forward Problem and Sensitivity

The classical forward problem of geoelectrics (includes electrical resistivity tomography, ERT and earlier techniques as vertical electric sounding, VES) is the calculation of potentials at a given set of electrodes (M,N) while current is injected at other electrodes (A,B) into the ground. Typically the physical domain (earth) is unbounded to the sides and the bottom because of which one needs ...

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. ...
