[Gate-users] Volume of the same name and copy number ("world_phys", copy 0) still exists and is being used.

[Changguo Ji]

Dear All Gaters,

I run several examples in 6.0. The Gate always give me a annoying waring like:

G4PhysicalVolumeModel::Validate() called.
  Volume of the same name and copy number ("world_phys", copy 0) still exists 
and is being used.
  WARNING: This does not necessarily guarantee it's the same
  volume you originally specified in /vis/scene/add/.

Anybody can help me to why?
