Hello Olivier,
 
next time, please ask questions via launchpad interface [1].
 
By default, O.save only saves attributes of C++ core. It does not save python-defined stuff (functions, variables), nor custom O.anythingNotCPlusPlus.
However, see documentation of utils.saveVars [2] / utils.loadVars [3]. They allow you to save custom data in the .xml file and use it after O.load,. Something like:
 
###
resume = False # change to Ture for the "resume" run

someVar = 1 # default value, overwritten below

def incrementSomeVar():
    global someVar
    someVar += 1

O.engines += [
    PyRunner(iterPeriod=1,command="incrementSomeVar()"),
    PyRunner(iterPeriod=10,command="save()"),
]

def save():
    saveVars("mySavedVars",someVar=someVar)
    O.save("test.xml")

if resume:
    O.load("test.xml")
    loadVars("mySavedVars")
else:
    saveVars("mySavedVars",someVar=someVar)
from yade.params.mySavedVars import *

print("TEST 1:",O.iter,someVar)
O.run(25,True) # simulating interruption
print("TEST 2:",O.iter,someVar)
###
 
Cheers
Jan
