Question Transportation manager has too many active navigators 

Forum: Biasing and Scoring
Date: 25 May, 2011
From: Dylan <Dylan>

I created a detector geometry with 30 alternating absorber and scintillator layers (a total of 60).

The width of the absorber layers is different to the width of the scintillator layers, so I had to create a macro which sets up 60 scorers, in turn, one for each layer, then runs an event, then outputs the value for energy deposited (eDep) in each layer, one by one.

However, on running the macro in UI mode, I get the following error:

### Run 0 start. Start Run processing.

---> Begin of event: 0

--------- Ranecu engine status ---------
 Initial seed (index) = 0
 Current couple of seeds = 9876, 54321
----------------------------------------
ERROR - G4PathFinder::PrepareNewTrack()
        Too many active Navigators. G4PathFinder fails.
        Transportation Manager has 9 active navigators.
        This is more than the number allowed = 8 !

*** G4Exception : TooManyNavigators
      issued by : G4PathFinder::PrepareNewTrack()
Too many active Navigators / worlds
*** Fatal Exception *** core dump ***

*** G4Exception: Aborting execution *** Abort trap

Does anyone know how I can get around this? When I run the macro with 3 absorber layers and 3 scintillator layers (6 total), the macro executes fine and I get the desired output. However, any more than this and I get this error.

Regards,

Dylan
