Velocity contour at interfaces problem
 

I have meshed the empty part part separately and the part with obstacles separately. The common faces are defined as interface in fluent and the solution was converged. Now everything is ok but when i generate a velocity contour at mid plane it is showing zero velocity near the interface zone.
Is there anything wrong in what I did or is this is an interpolation done by fluent??

Actual model is 3d but the attached image is contour on mid plane.....:confused:

Sorry, sorted it out!
