I am trying to calculate the heat flux across a thin SiO2 slab using the Tersoff potential in metal units, where I define two small control volumes, a source of 1,000 K and a sink of 200 K using NVT, and NVE in the intermediate transport region. I use the compute heat/flux found in the user guide, namely the example for solid Ar. From my understanding, this should be the net trans…
