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