I am a Dutch engineering student, normally I use Inventor, solidworks or autocad to make 3D designs.
Now I have to make some sort of a water turbine and I gotta simulate the spinning of the rotor itself. Well, now I haven't used Blender yet, I just downloaded it and I am struggling with everything.
I want to make some sort of a channel to let the water flow through on the rotor. But it got blocked by some sort of an invisible wall and I don't know how to fix it or what I've done wrong...
Here's the link to a video, which makes it more clear.
Also I would like to know how to fixate a rotor and let it spin because of the water.
Please let me know how to fix this and what causes the problem. And how I can make the rotor work.
Here is the .blend file itself:
