Thanks Makoto,

I think I must have described my case incorrectly. Or perhaps I don't understand the answer.

Whatever I do (and how deeply I delve into Geant4 source code),
I can't see a way how to have the "ConstructSDandField"
called for me by the kernel a second time.
(I am not sure I want this anyway - I would rather like to find a better place to introduce a new field)

Specifically, if I issue this set of commands:

/run/initialize
/run/beamOn 1      # RUN 0
/changeGeometry    # Simple command changing translation of one phys.volume
/run/geometryModified
[/run/initialize]  # Doesn't make any difference if present or not
/run/beamOn 1      # RUN 1

ConstructSDandField is called only once (or: master + once per worker),
for Run 0. Not for Run 1. (I am positive about this - print debugging on enter).
Are you suggesting it should be called twice (per thread and master)?

Thanks,
Jan

P.S. I am using Geant4 10.2.
