hi all!
After adding box with homogeneous perpendicular magnetic field inside I have the following output:
-------- WWWW ------- G4Exception-START -------- WWWW -------
*** G4Exception : GeomNav1002

Track stuck or not moving.

Potential geometry or navigation problem !
Trying pushing it of 1e-07 mm ...Potential overlap in geometry!
*** This is just a warning message. ***

I have no volumes overlaps…
Does anyone have idea where the problem can be? And how to fix it?
EDIT: I had 2 runs without this warning. Probably it happens rarely
cheers,
