Re: Question Warning: theListOfSecondaries() is not empty (Tomasz Sakrejda)

I do not get that message, using geant4-09-03-patch-01 and physics list QGSP. A 10 TeV mu+ generated 5493125 secondaries (139 seconds); a 100 TeV mu+ generated 20506638 secondaries (516 seconds). I am counting total particles produced, not just secondaries that make it through 100m of water after the 10m x 10m x 1km volume of water. I used a range cut of 1 mm, and an eventTimeLimit of 3000 seconds. Secondaries were tracked and the counts include them recursively.

I'm using G4beamline, which is how I can check simple things like this in just a few minutes of my time (it can also handle quite complicated beam lines and simple detectors). http://g4beamline.muonsinc.com -- Here's what I wrote to check this (units are mm and MeV/c):

    param eventTimeLimit=3000    
    physics QGSP
    beam gaussian particle=mu+ meanMomentum=100000000 nEvents=1
    box water height=10000 width=10000 length=1000000 material=H2O
    place water z=0 front=1
