hi i am new to cfd.

my question is this;
when i transfer my 3d model from gambit to fluent, and run it using k-epsilon, there is a statement that says "reversed flow .... " and when the iterations are done (1000) the residual doesn't converge, the Cd and Cl, well, it goes up and up......

hey azmo!
well, where do you have the reverserd flow? at the outlet?

yup at the outlet. i asked a friend, and the answer was, there may have been a problem with meshing, but how can there be problem with meshing?

*will message further when in front of own pc
