fix enforce2d/seaice/waves command

Syntax:

fix ID group-ID enforce2d/seaice/waves 

Examples:

fix 5 all enforce2d/seaice/waves 

Description:

This fix is part of the USER-SEAICE package; it is only enabled if LIGGGHTS was built with that package.

It should be used in sea ice simulations with quasi-3D wave effects, i.e., with the atom_style hybrid disk disk/waves and fix seaice/waves commands. Analogously to fix enforce2d, it zeroes out the z-dimension velocity and force on each atom in the group. However, to allow for wave-induced deviations of the disks orientation from the horizontal plane, this fix does not zero out the x- and y-components of the angular velocity, momentum and torque.


Restart, fix_modify, output, run start/stop, minimize info:
