! Test how many hexagonal panels are necessary to model all boundary conditions
! present in an array of hexagonal panels, three or seven.

! 1 - Two separate complete cups mirrored about xy-plane = two base areas
! 2 - Top and bottom cup share single base area
!B - Incorporate geometry changes from HexStiff-3V.txt - thickness differences in base and top of cups
!C - Fix geometry error - panel is 3/4" thick, not 1/2"
