Figure 2.15: The change in the eigenvalues of the discretised eigenfunction equations as
the constant nmesh2 is varied, with the constant order = 1. These two constants are
defined in constants.input. For (a), the run commands for the four tables are listed in
§2.3.9. Assuming that these are the first runs of the eigenvalue convergence command
for workedex, they will be allocated ecode values of 101–104. The tables shown can then be
generated via the commands convergence table workedex 101 4, convergence table
workedex 102 4, convergence table workedex 103 4, convergence table workedex
104 4. For (b), the run command is eigenvalue convergence workedex -1.5 3.0
800. Assuming that the runs for (a) have been done previously, this run will be allocated an ecode value of 105. The table shown can then be generated via the command
convergence table workedex 105 4.
