Optics and fluid dynamics simulation software

  1. Aug 24, 2014 #1
    I am doing "Schlieren imaging" visualization of a gas flow from the nozzle.

    could anyone please recommend a software to simulate a gas flow from the nozzle.

    in addition please recommend a software to simulate optics, like the propagation of a light beam through the optics and image formation.

    also tools to create such images: http://www.aor.com/images/ad61.gif

    thank you.

    CFD software can be fairly expensive, so what's your budget? Are you a student at a college/university perhaps?

    I don't know of any good free alternatives. Maybe have a look around on Google.

    I used OSLO once (ignore the hideous webpage) and it served me well enough for my small application. They have a free version for educational purposes.

    Try Inkscape. It's a great software package for creating vector graphics and it's free and open source.

    Look at OpenFOAM for the fluids which is free and very powerful - it's the internal solver of some high priced commercial software.

    For optics, maybe a raytracer is what you're after? Eg POVRay.

    Thank you!

    2tioker, yes I just found out about OpenFOAM, looks very promising. Also, "Blender" software for fluid dynamics, looks very fascinating, however as far as I understood it is more for Art purposes rather than for scientific evaluations.

    For simple optics designs you can try RayLab on the iPad. It is very simple and does not have all the capability of applications like Zemax, OSLO, and Code 5. But then again it only costs a few dollars. It is intended for learning about optics... Disclaimer-I am actually the developer for RayLab.

    Yea I'm not sure if the arty raytracers are accurate enough. Blender is primarily a modelling program, though it might have ray-tracing capabilities too.

    kghandi - Interesting to see simulation apps on mobile now.
