OpenFOAM based game - flight simulator.

astrohome · July 29, 2014, 12:22

Hi all!

I would like to experiment a little with gamedev, but I know just a bit of CFD and I was wondering - is it possible to use OpenFOAM as basic physic engine?

Basically, what do I need - calculation of lift, pressure (for destruction of elements after critical speed) and drag. Also, I would like to have a proper blade simulation to have advanced realistic behaviour. I suppose that for jet engines I could have more simple model (like a few parameters, force, consumption etc.) without losing too much of realism.

I thought that with reducing the complexity of basic mesh I could go real-time without a lot of side effects and still having enough computing power for graphics engine.

I suppose that for small planes I can use incompressible flow, but for advanced jets I should use compressible flow.

Idea is to have the most possible realism but not to load a CPU too much for calculations.

What do you think of these? Thank you a lot!

P.S. and sorry my English.

Hi,

what about Blender? It even has CFD on Board (based on Lattice Bolzmann Method).
It does not make sense to hope OpenFOAM(OF) can be used as Physics-Engine, OF has a different use. But again Blender should be your friend I guess http://www.wikihow.com/Use-Blender-Physics

Stick with the attractive stuff!

I wish this was the right venue but I hate to say that FV based fluid mechanics is really a poor base for what you're after.
