Interaction potential calculations

Hi,

Can you tell me how can we calculate amplitude of interaction potential in multicomponent fluid?

In the sample code given it was -1.2 how did it come about??
also can you tell me in the same code why they didnot use bounce back or any boundary condition?

stanley

Can any body please send me this paper?
