export my streamtracer result
 

Hello everyone,
Here I want to ask a question.Recently I start learn to use ParaView.
I find a problem,that I can not export my streamtracer out.Once I used CFX-post,I can export any part that I defined to a .csv file.
I tried Save Data command from File menu.But It can not get the streamtracer data.
What shuold I do?
Thanks.
