Hi,

thanks again, John. Your suggestions have helped, indeed. The G4PVPlacement option to check for overlapping is a nice thing. I found out that I had a very small overlapping in my geometry (in a completely different place from where we have been speaking about). So, I solved the overlapping and the checking in all other volumes gives no errors.

One question. Since I've included

/geometry/navigator/check_mode true

and

/geometry/navigator/verbose 1

I get from time to time, during run, the following warning:

*** G4Exception : InaccurateDistanceToIn
      issued by : G4VoxelNavigation::ComputeStep()
Navigator gets conflicting response from Solid.
*** This is just a warning message.

I've seen in the documentation that this happens when the navigator is not able to say if it's inside or outside the volume. Is it something that I do wrong that causes the warning? It happens only once every one million of events, or so. Is it a dangerous thing, or may I ignore the warning?

Cheers, Estela.
