Figure 1. Current SHiELD configurations. Each plotted cell is 48x48 actual grid cells. Heavy black lines represent cubed-sphere edges; red lines represent nested grids. Note that the global domain of C-SHiELD (top center) is slightly stretched as per Harris et al. (2019).
Although all configurations follow the unified “one code, one executable, one workflow” structure of SHiELD, the configurations are not identical owing to the need to tailor each configuration for its specific application. Further, given the rapid pace of SHiELD development and the staggered development cycle for some of the configurations, we do not expect all of the Tier-1 configurations to always have the very latest developments. The development paths of the different SHiELD configurations can be seen in Table 1.
