I don't see what this has to do with the pull code. The pull code is made for forces between
centers of mass of groups.
There are already some external force options in the mdp file.
But I don't see how you would set up an unbiased couette flow.
In reality the flow is generated by a pressure difference.
In a simulation you can apply an external force or impose a velocity profile.
But both these options make presumptions about the force/flow profile.
