Hi yade developers,

Here is just an interrogation about the xml files defining the Yade 
simulations:

Two things:

1/ With 10000 particles the xml files are about 40Mb, it is already a 
little heavy. With 100000 particles it would be about 400Gb and I 
imagine it is quite difficult to open such a file, to edit the first 
twenty line to define the simulation.

2/ In my mind, the definition of the particle assembly with its 
interactions and the definition of the simulation are two different 
stuffs. For instance you can perform different simulations from a same 
particle assembly, thus you don't need for each of these different 
simulations a different xml file defining the same initial particle 
assembly with the same initial interactions.
Or reciprocaly you can perform an identical simulation from different 
particles assemblies...

Consequently, my interrogation is:

Would it be interesting to split the xml file into two parts:
1/ the very first part defining the simulation itself could be kept as 
an xml file that we can edit manually,
2/ the second and heavy part could be saved separately as a compressed 
xml file or a binary file or something else ...

But, maybe you will tell me that it is not a problem thanks to python 
;-) in every case it is only a question, what is your opinion?

  Luc
