I want to relax a composite filled with Aluminium and Aluminia. The input file is as follow:
#Lammps 3d Al-Al2O3
units real
boundary p p p
atom_style charge
read_data al_al2o3_whole.txt
reax args: hbcut hbnewflag tripflag precision
pair_style reax/c control.file
pair_coeff * * ffield 7 3 7
neigh_modify every 10 delay 0 check no
velocity all create 300 27851123
fix f2 all nve
fix f3 all qeq/reax 1 0.0 10.0 1.0e-6 reax/c
thermo 100
thermo_style custom step temp epair etotal press lx ly lz vol
timestep 1.0
dump d1 all cfg 2000 Al-Al2O3.*.cfg id type xs ys zs id type q
dump_modify d1 element Al O Al
run 30000
The enclosure is the data file. Problem comes out when the calculation step is up to 700. The log file is as follow:
