GEOMETRY DEBUGGING

Dear Fluka experts,
i have defined a geometry in fixed format as
RPP body1 -500 +500 -500 +500 -500 +500 (the outer most body for
defining blackhole)
there are some other bodies in the geometry as well.however when i am
debugging the geometry along a co-ordinate axis for simplicity i get the
error showing that the points on surfaces of this box (+500 and -500) do
not belong to any region.
when i put the debugging limit as 499.999999999,there is no error (upto 9
decimal places), however i get the error at 499.9999999999(at tenth decimal
place).
In short i would say the points on the surface of this box do not belong to
any region.however as per my geometry they belong to Blackhole
i would appreciate any help.
Thank you
