The PM tree and the other related data structures are not closely related to the grids. An efficient, scalable parallel implementation requires that both the computation and the required data be evenly distributed across the available processors while minimizing the communication between processors. The dynamic and unstructured nature of the grid assembly workload and data structures and the global communication patterns that arise make this a formidable task.

Some bomb fuzes require a continuous supply of electrical power during flight.
For the laser-guided weapon of interest, a small wind powered generator located behind the forward suspension lug and extending from the fuze well can supply this power. The concern is whether or not the generator will stall during normal flight conditions. Stall could be possible if the wake caused by the lug or the warhead body disturbs the flow near the generator. Figure 5 shows the surface and highlights the blanked out cells. The surface grid on the warhead is depicted with the darker thick lines.
