Hi,
The only annoying thing I found with python scripting (compared with
complex routines in c++ engines) is that you can't really _save_ the
simulation.
By "save", I mean stop a simulation and write it to a file, and later
restart Yade, reload it and continue as if it had never been stopped.
It is not possible with most python scripts I have. Some variables are
lost, and in the worst case (see peri-triax.py->doneHook), c++ is
calling some python functions that will not be defined after reload. I
found a few workarounds, but they are relatively painfull (namely
emulate the previous context by redefining similar functions, but if you
need python variables that are updated during the simulation you are
toasted).
So, I have been thinking to PFC, where user defined functions and global
variables (PFC "fish" langage has ony globals anyway...) are saved at
the same time as particles positions and forces. I googled "save python
globals" or "save python context" a little but it didn't return anything
relevant.
Before I dive deeper into this question, do you think it is possible, at
least theoreticaly, to save a full yade session somehow?
Thanks.
Bruno
