it depends on what you mean by "fixed". if you mean moving but generally
staying in place, cartesian restraints can work (also depends on
which atoms are "fixed"). If you mean not moving at all, that's a bit more
difficult.
since the zero in space is arbitrary, another option is to move one chain
relative to the other using distance or other internal coordinate
restraints. again it depends on what you mean by fixed.
