hi! just wanted to know if cfx can do a rotating frame of reference using only a single domain? Im trying to compare results of this (if applicable) to the ones used on my previous fan blade simulation using Multiple domains (rotor-stator).
I used a big domain with 2 blades wall surface cutout from that and assign a counter rotating wall to make it stationary and let the domain be rotating. Then I used the 3 remaining surfaces of my cylinder (top-bot-radial surf) as an opening (coz im running this in an open ambient condition). When i start to run this simulation it wont run. Help pls? Thanks! |

thanks @highorder_cfd.
yes i dont have baffles on it so a rotating domain is applicable. I am already doing this setup but wont run. I have only 1 part and that is the big domain with a blade cut out. I make the walls of the big domain rotating as well as its domain is already rotating. The blade cutout surface is also rotating but assigned a counter rota wall to simulate it as stationary. I have no interfaces since I only have one domain one part. This setup wont run and I have to settle for a mesh deformation option inorder for this simulation to push through. Any more ideas? Thanks! =) |
