Hi, I am new to CFD. I am trying to run tutorial of Moving Reference Frame: Marine Propeller in Open Water. It has mentioned that most of the boundary conditions has already defined, all I need to do is to set the velocity. If I am using my own propeller I will need to do all the settings by myself so anyone knows what is the boundary conditions that has pre-defined?

By the way, how to set the flow to be reversed? When I run on the tutorial, it shows that "Reversed flow on 28 faces on Outlet". I have no idea how to set it to be reversed flow.

Thank you very much!

For the reverse flow, We don't set this, this means that some flow is coming inside from outlet boundary. This often happens in CFD when we have some circulation or flow separation at the outlet boundary. So it may be ok to have a reverse flow.


If you are done with MRF tutorial then you may know you have to create a reference frame in tools with desired RPM, then assign this reference frame to a rotating region under motion node.


Hope this help!!
