Dear All,
I doing simulation by taking Yukawa potential interaction among particles.
I am making wall by using command fix wall/harmonic or fix wall/region harmonic.
fix kg all wall/harmonic ylo EDGE 1 8.36e-4 yhi EDGE 1 8.36e-4 units box &
fix walls all wall/region reg harmonic 1 1
But i am getting errors :
ERROR: Expected floating point parameter in input script or data file (…/fix_wall.cpp:111) &
ERROR: Illegal fix wall/region command (…/fix_wall_region.cpp:39) respectively.

so is there a question somewhere? since you obviously want help, you
could at the very least show us the courtesy of making the effort to
formulate a precise question.
in general, when you are getting errors that usually means that your
input is incorrect. and it is *your* job to correct this. that is why
LAMMPS comes with a documentation. posting to the mailing list is
really only justified if the error is inconsistent with the
documentation. but the first input fragment is *definitely* incorrect,
there have to be 4 arguments following a wall face keyword. please
re-read the documentation with more care. i suspect the reason for the
second input fragment is similar.
...and for future posts, please read the mailing list posting
guidelines here: http://lammps.sandia.gov/guidelines.html
it is getting rather tiresome to be force to complain about too
little information. if you are not going to make a better in the
future, it is increasingly likely that your posts will be ignored.
