Note this is only implemented in the 4.1-beta releases. The rigid specification goes in the Geometry.Constraint block:
%block Geometry.Constraints rigid [1 -- 3] rigid [4 -- 10] %endblock "average" the force on atoms 1-3 and move 1-3 equivalently. "average" the force on atoms 4-10 and move 4-10 equivalently. For further details, please see the manual.
