"Global" sounds more appropriate for boundary conditions for me, but it 
is just matter of taste.
A difference between partial engines and TSController is that TSC is 
looping on all interactions and bodies for some tasks (defining 
boundaries stiffness, computing unbalanced force,...), even if it 
directly acts on 6 of them only. It is not a very clear distinction 
though...
