Good luck simulating fluid flow, that's all I can say.

Subject: namd-l: Shear flow: Lees-Edwards Boundary Conditions

  I am interested in simulating the shear flow in atomic fluid, at
constant pressure. I came across this informative tutorial
. I can see that the shear force is added to each atom, but I am not
sure if the Lees-Edwards Boundary condition is applied when
calculating the inter-atomic forces.

  What, if any, boundary conditions are applied in that particular
tutorial ? How can the Lees-Edwards boundary condition be applied in

Thank you in advance,
