<div dir="ltr"><div>You probably need to glyph the output from the particle path and the streakline filter to see the locations. Right now I don't think any cells are being generated by those two filters. If you don't have any points, you'll probably need to set termination time to something other than 0 for particle paths. I haven't tested the streakline filter but suspect it has similar behavior.<br><br></div>Regards,<br>Andy<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Nov 13, 2014 at 6:11 AM, Mykhaylo Zayats <span dir="ltr"><<a href="mailto:sylvynyo@gmail.com" target="_blank">sylvynyo@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi,<div><br></div><div>I have 2 files with data which contains x and y components of velocity field, I try to combine this data into vector and then create particle tracer, but it doesn't work.
