Can someone please answer Lili’s question. I also can not figure it out.
Hi All, May I ask a question following this thread regarding the meaning of the "args" of keywords "*pos*" and "*vel*" in "fix wall/piston command?" The doc says that *"pos* args = z z = z coordinate at which the piston begins (distance units) *vel* args = vz vz = final velocity of the piston (velocity units)" which seems: pos needs only one argument z, and vel needs only one argument vz (the z component of the piston). But in the Example part of the doc: fix walls all wall/piston zlo pos 1.0 0.0 0.0 vel 0.0 0.0 10.0 units box There are three args for each, what is the meaning of them? Thank you very much, Lili
