Problems of calculating the pressure inside and on the surface of droplet.

Hi, everyone,

I set up a droplet of water, how do I get the pressure P(r) that varies with the distance r from the center of mass.

In the theory section of materials studio, we know that the pressure can be calculated by the following formula

PV=N*kB*T+2*/3


Is this calculation feasible for droplets? If so, is the result the sum of all molecules less than r from the center of mass?

In addition, the pressure calculated by this method has no obvious peak value in the droplet compared with the calculation result of Ivring-Kirkwood, how can I calculate it more accurately?
