[lammps-users] Infused Rigid Particles moves diagonally

Hello All,

I am running MD a simulation where rigid particles moves in srd particle due to applied strain. Although I set the velocity 0.0 in all direction , the following npt command updates the velocity of the rigid big particles such a way that in movie it moves in diagonal direction !

Why this is happening ? Thanks in Advance.


compute csym all centro/atom fcc
compute peratom all pe/atom 
fix 5 all npt temp 300 300 1 iso 0 0 1 drag 1 
thermo 100
thermo_style custom step lx ly lz press pxx pyy pzz pe temp
run 1000
unfix 5
variable tmp equal "lx"
variable L0 equal ${tmp}
print "Initial Length, L0: ${L0}"
variable srate1 equal 0.01
fix 6 all deform 1 x erate ${srate1} y volume units box remap v
