hi all...
i'm trying to solve this problem with CFX5, but till now i failed due to wrong configurations, hope you can help me with these one,and i w'll be so greatful.
my problem explain how aerator works in sludge lagoon in waste water treatment plans, the aerator rotate at 43 rpm and i already made symmetry plans,but the main problem i had is what the boundary that i should add, the interfaces too, and why i can't run the problem with turbo mode?
the purpose for this problem is to simulate how water get in and out throught the aerator. and to know the dead point.

thanks.
