New Lunch Tutorial Shows How to Model Particle Tracing in Flow

Phil Kinnane | April 20, 2012

The manager of our Palo Alto Office, John Dunec, has been running some lunch tutorials that show the building of models. His latest one, which was presented last Tuesday, showed how flow in a building can be modeled.

Most of the flow travels down a hallway, but an open door means that some of the flow enters an adjacent room. Using particle tracing, John is able to show how much any possible airborne pollution would enter this room.

We extracted the particle tracing part of his tutorial, which can be viewed in the video below. This is a great example to get you up and running with particle tracing in COMSOL Multiphysics.

    Dear Colleagues,

    I’m interested in a model of a photon. I know the books of Prof. Thaller:
    Bernd Thaller
    Visual Quantum Mechanics
    Selected Topics with Computer-Generaded Animations of
    Quantum-Mechanical Phenomena
    Springer 2000
    however his models of the photons are not right.
    Do you know a model of a photon?

    Best regards

    Günther

    We are not aware of any quantum mechanical-based simulations of photons with COMSOL Multiphysics. Although such simulations may very well be possible. There are other quantum mechanical examples and papers available that may be a good starting point such as for a Conical Quantum Dot, Solution of the Schrödinger Equation for the Hydrogen Atom, and Modeling of the Quantum Well and Cascade Semiconductor Lasers using 8-Band Schrödinger and Poisson Equation System.

    These are links to these models and papers:

    Hi … waw that example I really liked, I wonder if I can work with “particles” of 10 or 20 cm, for the simulation of a slab or mechanical filter for domestic water treatment …. Peru’m sorry I do not speak English. In advance thank you very much
