Free rotating propeller problem
3 Attachment(s)
Hello, all.
I have some problems with free rotating screw in a tube which is located inside the ship's hull. The goal is to investigate how much power can we get from the flow from the ship's movement. I have created two regions for the ship and for the screw respectively. I tried to apply both DFBI free motion and one DOF rotating motion. In both cases the screw is rotating in the wrong direction and almost stopping the flow. Does someone know what am I doing wrong? Thank you in advance!

I think you need to delete the task since it was originally made in a different version. If it doesn't help, then the time step is to blame. Make it smaller, but I think the problem is in the version or when restarting there was an error that persisted. To eliminate it, it is better to create the task again. This happened in my example, when I built the task in version 13 and launched it in version 17. We had to build it again. https://youtu.be/xDyWPHa41KE |
