Hello Feflow's user!

I meet difficulties using the particles tracking for a "[i]Multiple pathlines around a single well[/i]".
The error message is the following "[i]no single well present within the study area -- current application is not applicable[/i]". While I have a well selected throught the "[i]starting point selection mode[/i]" (using a .trp file).

Is anybody can help me, and tell me what is the right thing to do?

Thank a lot.
