Hello
I have a question about displace_atoms command:
Can I use “args” of this command as below?
displace_atoms all move -0.1cos(acos(x/(sqrt(x^2+y^2)))) -0.1sin(asin(y/(sqrt(x^2+y^2)))) 0 units box
(As is visible, the args are variable according to atoms position)
Thank you for your help

no!
please see the documentation at
http://lammps.sandia.gov/doc/displace_atoms.html
does it say anywhere in there, that you can do this?
displace_atoms all move -0.1*cos(acos(x/(sqrt(x^2+y^2))))
-0.1*sin(asin(y/(sqrt(x^2+y^2)))) 0 units box
(As is visible, the args are variable according to atoms position)
however, you *can* do such an operation by defining suitable atom-style
variables.

i suggest you first experiment with some trivial test examples that
contain only a few atoms until you have understood how to do this correctly.
