Setting up Flow around a Wing Simulation help
I am trying to model the flow around a wing in order to measure the lift and drag forces at different angles of attack.
At present I am using CFX through the ANSYS Workbench application. I am pretty new to all this and I am struggling when it comes to setting the domains.
At present I have modelled my wing in CATIA and modelled a domain around the wing. Once I load this into CFX it recognises this as 2 bodies. I am able to specify the inlet, outlet and walls of the domain and I set the wing as solid but once I have run the simulation the flow doesn’t seem to flow through the domain and around the wing, just straight through with no deviation.
Does anyone know what I could be doing wrong? Do I need to model the domain separately in ANSYS?
Thanks for your help
Get rid of your wing domain. You should only keep the fluid domain.
Set the surface of the wing cutout as a no-slip wall.
Thanks for the reply.
When i setup the problem using only one domain i get an error when solving it
stating that "2 isolated fluid regions were found in domain Default Domain"
Would anyone know why this is occuring or how to solve this? I think it is because I have 2 bodies imported, the wing cutout and the windtunnel domain. Would this problem be solved if i just imported the wing geometry and created a domain in the design modeller section of workbench?
If not anyone know how i could get around this?
Thanks for your help!
I always use the Enclosure feature in Workbench to make my fluid domains. Don't forget to suppress your solid bodies before importing them in CFX.
