hi all

i’m trying to make a cell structure including different input data structures; one as a basement and the other ones as small particles at specific position (like as metal alloy). how can i import multiple input data by lammps? is there any software that i can make this?

you can’t do this. You can only read one data file
for a single simulation. You can pre-process the multiple
files into one data file. The “data” tool in Pizza.py could
help you do this, with a short Python script.

Also check out topotools:

(You can also merge data files with a combination of ltemplify.py and
moltemplate.sh. There's an example of this here:
http://lammps.sandia.gov/threads/msg41643.html
but this currently does not remove overlapping molecules.)

Anyway, try using topotools first!
