I was thinking of trying out a simulation where I can

somehow make the boundary act elastic, perhaps via

some trick with "fix spring", such that the volume of

my simulation isn't necessarily fixed. (Whether this

is a good idea is another story, but I'll leave that

for another time.)

Now as I've understood it, NVE integration simply

means that no scaling is applied to Newton's laws, so

energy (the "E" in NVE) is conserved, but the

conservation of the "N" and "V" in NVE is a byproduct

of periodic boundary conditions rather than something

enforced by the intergration algorithm itself. Is this correct?
