Setting up Flow around a Wing Simulation help
Hi,
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.
