streamlines

Newbie

Hi, y'all fluent gurus.

I'm running a (very) simple case but I'm not sure of the results.

The case is the following, I have a rectangular (unbounded) domain in which a circle (2D sphere) is in the middle.

A viscous liquid is laminary flowing downward and I define the boundary conditions at left and right as axis ( I've also tried interfase and others) and an outflow in the bottom.

My problem is that the resulting streamline function is always 0 at left and goes to a certain value at right. To my knowledge the streamline function must have symetric values as the case is.

I'm right or fluent is? Am I using the right boundary conditions?, any advices?

Thanks to all.
