Here are two examples of what is printed while the robust solver runs.
Example for case 1:
Processing contingency "SING OPN LIN 75 558-1529(1)" (#75 of 862):
OPEN LINE FROM BUS 558 NAME1 380.00] TO BUS 1529 [NAME2 380.00] CKT 1
Successful solution not achieved: Iteration limit exceeded
Largest mismatch is 113.04 MW or Mvar at bus 160396 [NAME3 330.00]
Total mismatch is 432.00 MVA

Attempting to solve with locking 1391 generators with var band smaller than 4.00...
Solution failed. Restoring case and settings to ORIGINAL state.
Robust power flow solution UNSUCCESSFUL.
Testing RAS conditions after application of contingency [SING OPN LIN 75 558-1529(1)]
Example for case 2:
Processing contingency "SING OPN TIE 240 2786-20234(1)" (#240 of 697):
OPEN LINE FROM BUS 2786 [NAME1 380.00] TO BUS 20234 [NAME2 380.00] CKT 1
Testing RAS conditions after application of contingency [SING OPN TIE 240 2786-20234(1)]
Implemented action for RAS: [SPS1]
Warning: Bus 1223 [NAME3 220.00] is a type 3 bus with no plant or machine data
Successful solution not achieved: Iteration limit exceeded
Largest mismatch is 18.53 MW or Mvar at bus 1223 [NAME3 220.00]
Total mismatch is 76.24 MVA

Attempting to solve with original settings...
Maximum mismatch changed from 18.72 MVA to 18.72 MVA at bus 1221.
Robust power flow solution SUCCESSFUL, but control option adjustments required!
