The whole system will rotate

I am using LAMMPS to simulate a 2D eam system recently. I have met a problem.
When I used boundary as “s s p”, the whole system will rotate.
I had use the commands:

velocity all create ${temp} 76329 loop geom mom yes rot yes

velocity all create 100 49284121 mom yes rot yes

fix 0 all nvt temp 100 100 0.1

May anyone give some advice to make the system not rotate?
Thank you in advance.

regards,
Nili

i don't think that would be possible based on the extremely limited
information you provide.
