Hi Nishant,

> Is there a particular reason that the simulation continues with empty
body fields?

There are several reasons, e.g.:
1) performacne. O.bodies is internally std::vector, which is "cheap" for access by index, looping and appending to the end. It is "expensive" for "hard deleting" items from the middle, therefore the deleted item is just set to None/nullptr.
2) as a consequence of current behavior, O.bodies[b.id] is always b, which some YADE internals depends on and which would not be true with "renumbering"

cheers
Jan
