Hi John. Thanks for the advice. I tried your suggestion to comment out the ifdef G4DEBUG_FIELD lines, but it didn't result in any changes in the output. I also tried setting some output flags for the field calculations. I was able to determine that the forces from the EM fields that the UCN encounter are identically zero, as they are supposed to be. I am a bit lost trying to track down the gravitational field incorporation, however.

The code was initially written for Geant4.9.3. However, before transferring the code to my current computer, Geant was upgraded to the current version, 4.9.6.p02. It worked on that computer, so I don't think there's a version incompatibility.
