I’m having a problem with stream lines in my simulation. I’m trying to simulate the propeller spinning and for some reason my stream lines are all over the place. At first I thought that the propeller was maybe spinning backwards, but I have since proved that not to be the case. I’ve tried all sorts of things like changing the bounding box size and nothing seems to work. Any thoughts? Thanks!
Take a look at more of my screenshots and simulation here: SimScale
I have modified your project by defining an inlet velocity which was zero for every direction. Works fine now!
Cheers and happy SimScaling!
Ok, thanks! So is there a way to make it so that the propeller is spinning alone, without any airspeed? As if the drone were standing still with the propeller spinning?
This is indeed possible! Please have a look at the project right here: Propeller Project
In general defining:
- Inlet - total pressure
- Outlet - static pressure
should be stable. Let me know if you need a hand!
