fix oneway command +

+

Syntax: +

+
fix ID group-ID N oneway region-ID direction 
+
+ +

Examples: +

+
fix ions 10 oneway semi -x
+fix all 1 oneway left -z
+fix all 1 oneway right z 
+
+

Description: +

+

Enforce that particles in the group and in a given region can only +move in one direction. This is done by reversing a particle's +velocity component, if it has the wrong sign in the specified +dimension. The effect is that the particle moves in one direction +only. +

+

This can be used, for example, as a simple model of a semi-permeable +membrane, or as an implementation of Maxwell's demon. +

+
+ +

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

+

No information about this fix is written to binary restart +files. None of the fix_modify options +are relevant to this fix. No global or per-atom quantities are stored +by this fix for access by various output +commands. No parameter of this fix can +be used with the start/stop keywords of the run command. +This fix is not invoked during energy minimization. +

+

Restrictions: none +

+
