Question FarOutsideCurrentVolume exceptions 

Forum: Event and Track Management
Date: 10 Sep, 2009
From: Johannes Hoppenau <Johannes Hoppenau>

Hi,

I am having a Problem with FarOutsideCurrentVolume exceptions. My geometrical setup it the following:

There is a core (WCCore) surrounded by an annulus (WCBarrelAnnulus). The annulus is divided in cells (WCBarrelCell) using Z-Phi replicas. All Volumes are polyhedra and filled with water. Everything is embedded in the WCBox volume. I am appending a dump of these volumes.

When I run the simulation with /geometry/navigator/check_mode true it crashes with the following output:

*** G4Exception : FarOutsideCurrentVolume

Point is far outside Current Volume !

*** G4Exception: Aborting execution *** Abort

The point where the error occurs is different for every run, but is outside of annulus every time. How can I figure out, why Geant4 assumes, that the particle should be inside the annulus?
