[gmx-users] energygrp-excl with wall setting

[Ahmed Mohammed]

Happy new year to all
I'm simulation a mixture of water and hydrocarbons on a slab and I'm using
wall setting (nwall=2).
I would exclude the interactions between water and the wall. I used
  energygrp-excl = water wall0  water wall1
But I see the interactions between the walls and water before and after
defining energygrp-excl are the same before.

Any ideas how to stop the interactions between the walls and water
molecules?

Thank you
