>>> Solution proposed by Jan Stránský <<<
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
