[gmx-users] say something about the pull geometry of cylinder

[lammps lammps]

 Hi ,

 I can not fully understand the picture of parameter of pull geometry of
cylinder.
Who can say something about it, Thanks in advance.

 Thanks in advance.

-------------------------------------
pull geometry

cylinder
Designed for pulling with respect to a layer  where the reference COM is
given by a local cylindrical part of the reference group.

The pulling is in the direction of pull vec,which should have only a
z-component.

>From the reference group a cylinder is selected for determining the COM,
with the axis given by the x/y location of the group to be pulled and two
radii.

The radius pull r1 gives the radius within which all the relative weights
are one, between pull r1 and pull r0 the weights are switched to zero.  Mass
weighting is also used.
