Hi All,

I have added an external potential similar to wall/lj93 but with

distance away from the wall dependent on other two dimensions. This is

done to model a rough wall with a sinusoidal function of the form:

E = epsilon*f(z - z0(x,y)), where f is a function of z distance away

from the wall and the position of the wall z0 is dependent on x & y

direction as well.

To account for x & y forces arising from this type of potential, I have

added 2 lines similar to the following existing statement for z-direction:

f[i][dim] -= fwall;

My question is: I want to exclude these additional forces due to wall

from the pressure calculations for pxx & pyy. I am struggling a bit to

find the files and actual statements where forces due to fix are added

to calculate virial and then pressure. Any help will be much appreciated.

Thanks,

Jeetain
