how to get complete streamline(pathline) in pump?
 
1 Attachment(s)
hallo, friends,

I am simulation a pump with front and backward guide vanes. the pinch of turbo and guide wane are different. (two blades on turbo, 4 blades on guide vane).

I try to draw streamline in CFX-post, but only a few can go through the sliding interface between turbo and guide vane, most of the streamlines are "cut" or say "stopped" by the interface.

and another problem is that, when I try to draw streamline with "velocity in Stn Frame", the streamlines will be stopped by the blade.

How can I get "complete" streamlines in a pump??
Can you give me some advice.
I am very thankful to that.

Best Regards,
