I have searched for any computerized graphics visualization of a quadcopter or other multirotor and all I am able to find are a very few models of a single propeller. (Simscale has an example of a single quad arm and rotor here:) Has anyone seen a full multirotors visualizations produced by computational fluid dynamics (CFD)? NOTE: I am not looking for a schematic animation. Those are abundant.
You can make your own using free software.
Let’s take Fusion 360 as an example, in its simulation suite it has a Computational Fluid Dynamics study option.
If you’re willing to design an accurate-ish model of the aircraft you want, or pay someone to design one for you, you can run the CFD simulation and get the results for yourself.
This is obviously CPU intensive so there is an option to run it in the cloud on Autodesk’s servers.
Thats definetely a late response but in case anyone is interested in the same topic, I found SimScale platform quite handy when trying to test a couple of CFD and FEA models.
With respect to drones, they provide this public (and free) Quadcopter Drone CFD simulation model.
If you are new to simulation, it might definetely be a good starting point.
