Question Problem in G4Orb 

Forum: Geometry
Date: 03 Jan, 2007
From: <jgzm6@umr.edu>

Dear G4s: I am using the G4Orb in my Parameterisation as following:

solidNano =new G4Orb("nano", NanoWidth*0.5) LogicNano =new............

I never instantiate the fuction G4Orb::DistanceToOut(...)but the following worning message came out. what's wrong with my using G4Orb?

-------------------------------------
    *** Dump for solid - nano ***
    ===================================================
 Solid type: G4Orb
 Parameters: 
    outer radius: 5e-05 mm 
-----------------------------------------------------------
Position:

p.x() = -2.61756492392351e-06 mm p.y() = -4.992317579421979e-05 mm p.z() = -9.474848146062698e-07 mm

Rp = 5.000072854454659e-05 mm

Direction:

v.x() = 0.6967354558785861 v.y() = 0.716168068935222 v.z() = 0.0407799161261308

Proposed distance :

snxt = 9e+99 mm

*** G4Exception : Notification
      issued by : G4Orb::DistanceToOut(p,v,..)
Logic error: snxt = kInfinity ???
*** This is just a warning message.

Is this a serious worning?
