Parameters for the iterative solution of linear equations for neutron fluxes by the
CPM. The value in < > shows defaulted value used when ITMINN ≤ 0 is specified.
(cf. Sect.7.4)
1 IEDIT Edit control
= 0 No edit
plus 1 Print reaction balance and flux distribution
plus 2 Print macroscopic cross-sections
plus 4 Print collision probabilities
plus 8 Print fixed source distribution
Note:
If the user wants to print out macroscopic cross-sections and collision
probabilities, IEDIT=2+4=6.
2 ITMINN Maximum number of inner iterations per an outer iteration
for the eigenvalue problem, but for the fixed source problem in
thermal energy range
3 ITMOUT Maximum number of outer iterations for the eigenvalue problem
4 ITBG Minimum number of iterations before extrapolation
5 LCMX Number of iterations for testing over-relaxation factor
6 ITDM Minimum delay between extrapolation
7 IPT Control of monitor print at each iteration
= 0 suppress print
= 1 print record
= -1 print detailed record
1 EPSI Convergence criterion for inner iterations
2 EPSO Convergence criterion for outer iterations
