NEMD problem

Hi Users,

I am trying to set up an NEMD simulation. In the set up I have an elongated simulation box say along z-direction. I put a heat source around the center of the simulation box in the region z = -2.5 to 2.5 A. At the two ends of the simulation box along z-direction I put two sinks of width 2.5A each. I have water molecules in my system. In the source region I need to heat it at some rate and from the sink I need to take out heat at the same rate. Now the problem arises in heating or cooling these source and sink region. If I group these regions then its a static one. So it does not serve the purpose. Can any one suggest me how do I heat the source and cool the sink?

kind regards

You can use fix heat. It can be used multiple times on different
regions, i.e. to heat one region and cool another.
