Hi

hi!

What is the use of the array virial[ ]?

it may be too obvious, but it contains the "virial".

and what are values stored in the following arrays virial[0] , virial
[1],virial [2],virial[3],virial [4],virial[5]... ?

those are the components (it is a symmetric 3x3 matrix
so you need to consider only xx, yy, zz, xy, xz, and yz).

or what is the use ? how does it affect the system ..?

please pick up your favorite text book on MD!

or take a seak peak at:
