Syntax:
fix ID group-ID planeforce x y z
Examples:
fix hold boundary planeforce 1.0 0.0 0.0
Description:
Adjust the forces on each atom in the group so that it's motion will be in the plane specified by the normal vector (x,y,z). This is done by subtracting out components of force perpendicular to the plane.
If the initial velocity of the atom is 0.0 (or in the plane), then it should continue to move in the plane thereafter.
