[Getdp] GlobalTerm

Hello!
While playing around with capacity calculations, I found out that I know
nothing to little about it.
While this seems to work:
>Galerkin { [ epsr[]*Dof{d v} , {d v} ] ; In Vol; Jacobian Vol ;
Integration Int ; }
>GlobalTerm { [ -Dof{Q}/eps0 , {V} ] ; In Grouped ; }
the following delivers false charges:
>Galerkin { [ eps0*epsr[]*Dof{d v} , {d v} ] ; In Vol; Jacobian Vol ;
Integration Int ; }
>GlobalTerm { [ -Dof{Q}/eps0 , {V} ] ; In Grouped ; }
although the potential is correct in both cases.
 
only after changing the second line to
>GlobalTerm { [ -Dof{Q}, {V} ] ; In Grouped ; }
the charges are correct again.
 
This seems rather confusing, especially if one does not understand how
GlobalTerm works.
Obviously it is nothing like a Galerkin Term, still it has two parts?
 
Thank you very much for your replies,
nice greetings,
Bernhard
