Question #270775 on Yade changed:
https://answers.launchpad.net/yade/+question/270775

    Status: Open => Answered

Jan Stránský proposed the following answer:
See my first answer, using O.run(), -x option works exactly as it should =
exiting just after O.run() is called without running anything :-) to run
all the simulation and exit after it is finished, you have several options:

1)
your original script, just run it:
O.run(someVeryBigNumber,True) # will wait for O.pause() from PyRunner to
finish the script

2)
nSteps = int(finalTime/O.dt) # if you have constant O.dt and known total
simulation time 1.0e-7
O.run(nSteps,True)

3)
def stopCond():
   if O.time<1e-7: # or another condition
      return False
   else:
      # do the finishing here
      fe.close()
      fp.close()
      yade.timing.stats()
      ft.close()
      return True
while not stopCond():
   O.run(50,True) # you can choose any number instead of 50

4) like 3)
def stopCond():
   if O.time<1e-7:
      return False
   return True
while not stopCond():
   O.run(50,True)
# do the finishing here
fe.close()
fp.close()
yade.timing.stats()
ft.close()


cheers
