Paul,

I wish you would create a separate project for the simulation effort so that others interested could like and follow this effort. I'd love to learn your approach to this. Maybe a Github project

I look forward to seeing how you would use OpenGL for this purpose. I've been looking at Modelica to see if I could do it there but the learning curve seemed steep and I couldn't sort out the basic open source capabilities from the commercial Add-on modules. 

The OpenGL will be just used for visualization of the paths. The main algorithm is planned to be like that: I´ll generate a discrete 3D-Space array and propagate the photons or waves within that. If photons take up the same cell in space but are 180° phase shifted AND hit a wall, they will not be reflected by the walls but just continue propagating.
I don´t know the result of this yet, will post results when finished.
Open sourcing: ok, but I am using my own toolchain now, have no time and effort to make the code clean and universal, maybe later.

Suggestion denied. I suggest you to find another hobby than trolling. Thank you.
