Hello.
My name is Mizuki Koyanagi and I resarch “Granules movement simulation” in Seikei University.
I try to develop a system to deal with two types of particles(atoms) with different sizes and rotate (as a mixer) by LAMMPS.
I would like to use below the code, but I am in trouble because I cannot add a particle(atom).
What would you suggest I do?
↓↓code↓↓
variable name string mixer
thermo_modify flush yes
variable seed equal 14314

please *always* report the LAMMPS version you are using the platform
you are running on.
what you do mean, by "cannot add a particle(atom)"?
what is that you expect should happen with the input you quote and
what is it that you get instead and how do you determine this?
when i run the input below on my linux x86_64 machine with the latest
version (12 Dec 2018) it inserts 1000 particles via fix pour just as
requested.
so where is the trouble?

Hello.
Thank you for reply.
Sorry for my lack of explanation.
I am always using on Windows10 with “LAMMPS (20 Apr 2018)”.
I mean that I would like to use paricles of two differently,with 1000 big particles for one and 500 small particles for the other.
However, I cannot know how to add 500 small paricles.
So please tell me how to add 500 small particals to this code.

just add a second fix pour with corresponding settings.

Thank you for your reply.
I cannot understand you sent "e$B!Ie(B.
I tried to add
“ins all pour 500 1 42424 region insreg &
diam range 0.01 dens 0.5”,
but it was sent error mesage "Expected floating point parameter in input script or data file ".
Please tell me specific solution(code).

as you should. this is not correct input.
Please tell me specific solution(code).
please read the documentation and be more careful and thorough. i have
no time to help people, that cannot check their input to be
syntactically correct.
also, after to correct the syntax, please read up on what happens, if
you create two fix instances with the same label. this is most
certainly not what you want.
