Hello everyone,
I am trying to impose as a boundary condition in a wall rotational movement. My problem is 2D and i have rotate my domain so the rotated wall be in the x - axis as tutorial says. Even though it does not work. Any suggestions?? Thanks in advance |

It's a reactor. Imagine tha i have a plate where i want to impose rotation. Something like the scetch below
|<-rotated plate ___________________________|________________ ^ x-axis (symmetry) but it doesn't work at all. I have tried all the solution that manual provides!! If you have any idea we can discuss it. What is your problem about? |

Because my previous scetch was rather bad i am posting a new one. I hope it will be more helpfull than the other one.
_ _ _ _ _ _ _ _ _ |_ _ _ _ _ the line with spaces is x - axis of symmetry and the one line normal to x - axis (the little one) is the plate where i want to impose the rotational boundary condition (of course is larger in reality). Thanks |

what I supposed form your sketch is you have 2d Circular domain with a wall (rotating Plate) is moving ..unlike Stirred tank wall is stationery and moving part is shaft with turbine. I reccom you first use MRF moving rotating frame..mean your domain fluid is MRF mention your rotational speed similar one to your rotating plate..and your rotating plate is your moving wall..IT it wont be work try sliding mesh... if you have still problem you send me your CAD file so I can Impose boundary condition and send back to you..
