Optics and fluid dynamics simulation software

Click For Summary

Discussion Overview

The discussion revolves around recommendations for software to simulate gas flow and optics, specifically in the context of Schlieren imaging visualization. Participants explore various tools for computational fluid dynamics (CFD) and optical simulation, as well as image creation software.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks software recommendations for simulating gas flow from a nozzle and optics for light beam propagation and image formation.
  • Another participant mentions the cost of CFD software and suggests checking for free alternatives, while also recommending OSLO for optics simulation, noting its free educational version.
  • OpenFOAM is proposed as a powerful and free option for fluid dynamics, with a suggestion that it is used in some commercial software.
  • Blender is mentioned as a fascinating tool for fluid dynamics, though it is noted to be more art-oriented than scientifically rigorous.
  • RayLab is suggested for simple optics designs, with a disclaimer from its developer regarding its educational focus and limited capabilities compared to more advanced software like Zemax and OSLO.
  • Concerns are raised about the accuracy of artistic raytracers like Blender, with a note that it may have ray-tracing capabilities.

Areas of Agreement / Disagreement

Participants express a variety of opinions on the suitability and capabilities of different software options, indicating that multiple competing views remain regarding the best tools for simulation in fluid dynamics and optics.

Contextual Notes

Some participants highlight the cost of software as a limitation, and there are differing opinions on the accuracy and application of artistic software like Blender in scientific contexts.

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.
