hi
i was trying to simulate a liquid film using lammps. i employed NVT ensemble. i used compute stress/atom and fix ave/spatial to find the pressure distribution. but i am getting negative values for pressure in some bins.
Thanking you

Negative pressure is often legit, especially since
pressure fluctuations are large. how do you know
it is wrong?
