    • This non-zero pressure is a result of the finite box size. Simulations carried out in a fully relaxed sample showed no quantitative differences in shear stress relaxation or temperature rise within the error bars.

    • This constant compliance was determined by both straining the system without allowing relaxation, and by monitoring the stress and strain during dynamic relaxation of a sample from 4 GPa shear stress. This dynamic calculation was achieved by monitoring dislocation displacement, and thus plastic strain, as described in Sec.. In both cases linearity was observed over the entire range of stresses discussed in this paper.
