Description Stephan.Wynhoff 2003-07-11 07:23:15 CEST

For each particle that is identified as looper Geant4 5.2 prints FOUR lines:

G4PropagateInField: Warning: Looping particle.
 G4Transportation is killing track that is looping or stuck
   This track has 0.00108415 MeV energy.
G4PropagateInField: Warning: Particle is looping -  tracking in field will be stopped.

Thanks to this I cannot see anymore at which event the job is. Can this warning be
- reduced to one line or
- be switched off and reduced to some statistics per event.

For your information, with Geant4 5.2, more tracks are abandoned as the
threshold number of 'field-substeps' has been reduced from 10,000 to 1,000.
This is a parameter of G4PropagatorInField that can be tuned by the user, using
the following method:
     inline void    SetMaxLoopCount( G4int new_max );
     // A maximum for the number of steps that a (looping) particle can take.

I have created a revised version of G4PropagatorInField.cc which makes this
report optional (on condition of verboseLevel > 1).  I am making it available
for your tests (see "File" above) and further testing by Geant4 system testing
for future release.
