"extra" value for bodies

> I guess Christian has in mind to use e.g. clump volume in some c++

No, in my example I need clump volume to calculate porosity. This is done in
python code.
But I dont know what other users want to do with their ex

Another option is to keep the data outside bodies in a separate table.
Saving a table is no big deal, and it doesn't waste memory when the
table is empty.

Yes that one too. I aprooved when I read it but didn't recall it.
Not sure it would be easier than void pointer though, since it would need a lot
of typecasting.
Your example is ok in python but the vector3 can't be used in c++ at this
poin

The problem is not how to access the extra variables in python but how to
implement them in c++.
For storing arbitrary types, I see at least two ways:
1/ void pointers + some typecasting
2/ add template parameters to the class Body
(2) is forbidden in yade as serialization and python wrapping don
For further explanation (my first ideas):
We could first make an easy-to-implement feature, later it could be extended.
Lets say we just want to let extra variable be int or float. Also for the
start, there is
only one extra value allowed for one body (as said, later we can extend if
needed)...
