Hello,

See O.save [1] and O.load [2].
Be aware that the saved files very likely will not work on different version of Yade (i.e. after update or on a different machine)

Cheers
Jan

the simulation.
So if i were to reopen it and continue running it, where would i do that from?

It depends on the use case. And also definitions like "from where" etc.
O.save saves the simulation to a specified file.
O.load loads simulation from specified file.

### script1.py
O.bodies.append(sphere((0,0,0),123))
O.save("/tmp/file1.yade")
###

copy /tmp/file1.yade to /tmp/file2.yade
you can use directly file1.yade, just that you can copy, move, ... the files freely

### script2.py
O.load("/tmp/file2.yade")
b = O.bodies[0]
print(b.shape.radius) # should print 123.0
###

Cheers
Jan
