[SOLVED] Help with read_data command

Submitted by zamir on Thu, 06/14/2012 - 20:13

Hello all,

I am generating a txt file for the read_data command and I am getting an error that I just cannot figure out! If someone could be so kind as to take a look at this for me, it would be very much appreciated.

My input file is the following:
##
units si
atom_style hybrid granular molecular
boundary f f f
newton off
communicate single vel yes
read_data read_data.txt
mass * 1.0

###################################
# no boundaries for now...
fix 1 all gravity 9.81 vector 0.0 0.0 -1.0
fix 2 all rigid molecule
neigh_modify exclude molecule all
pair_style gran/hertz/history 1777777.78 2285714.29 0.5 0.0 0.5 1
pair_coeff * *

compute 1 all ke
thermo_style custom step atoms c_1
thermo 2500
thermo_modify lost ignore norm no
compute_modify thermo_temp dynamic yes

timestep 0.000001
dump 1 all xyz 2500 trajectory.xyz
run 25000

The data file is attached.
What is strange is that if I truncate the data file to 100 atoms or so, it works, but in its complete form, it stops with an error.

Any help would be greatly appreciated!
Zamir

edit: data file now attached!
edit again: The error I get is the following:
ERROR: Did not assign all atoms correctly

ah! I figured it out. I was creating a few atoms just beyond one of my box boundaries. Thanks to all who looked at my post. Later,Z

yeah, the input file was just jacked from another post on this forum, don't pay it any mind. However, I am attempting to perform a hybrid granular molecular simulation, it seems like the easiest way to model random bonded particles. I could not get the bonded particle model you posted last November in developer's forum to work with non-lattice atoms, so I am here now.

Thanks,
Zamir
