Card-006-3 Specification of meshes to superimpose 3(6I4)
Specify blocks of points by left column number and then right column number
to give limits along rows, top and bottom row numbers for column limits, and front
and back plane numbers for depth limits in that order. If only one row is involved,
for example, then that row is repeated as limits. Only 4 entries among 6 are valid
for each specification in 2-D geometry. Data is read until zero value is encountered
on the first column number. The entry ‘000600060005001500020002’ places the
new material along column 6 from row 5 through 15 and on plane 2 only.
Remember that each mesh point has an associated volume around it (as mesh
points do not lie on material interfaces); specifying a single mesh point here, say
‘000600060005000500020002’ does involve an associated volume.

============= Section 008 : Macroscopic cross-sections =============
Macroscopic cross-sections are supplied by two options. One is to read from this section
described below (KMAX>0). The other is to read from an I/O unit (logical 31) where the form of the
