Description ersmark 2003-08-13 04:10:04 CEST 
When shooting 202MeV protons against a water cylinder (r=10cm, length=10cm)
Geant4 terminates after a few thousand events with:
-----
Unrecoverable error for:
 - Particle energy[GeV] = -2.65343e-17
 - Material = Water
 - Particle type = neutron
GetHadronicProcess: No model found for this energy range
