Negative values for time in particle tracing!!

Please login with a confirmed email address before reporting spam

Hi all,

I tried to release 1000 particles from one of my boundary in my geometry and after running the program.

I calculated the "time stop" for the particles in order to know that when each particle hitter the outlet.
Some of particles they had negative values for time!

How is it possible? Did you confront to a problem like this? evaluating negative values?
what does it mean?

Hope to hear from you.
Thanks
Sepideh
