reverse flow
 

hi all,
i have a problem with a simulation in fluent. the problem is the message on reverse flow. i know that the flow on the face is opposite respect on the boundary condition; but how can resolve it? the model that i used is:

• pressure based
• k-e turbolence model
• incompressible fluid

any suggestions are welcome
thanks

what does your domain / geometry look like?

There are many, many, many, many ... topics with this problem.... and always the first answer is.... extend the domain at the outlet... till the region of fully-developed flow... the other option is to chose other BCs...

Advice: Look for older topics...
