Hi all,

I need the NWT solve table in the MODFLOW .out (the block under SOLVING FOR HEAD with columns like Residual-Control, Outer-Iter, Max.-Head-Change, Max.-Flux-Residual, L2-New/L2-Old).
My model (MODFLOW-NWT) runs, but this table doesn’t print; the LRW example does.

Current NWT (summary):
1.0e-4 500 400 1.0e-5 1 1 1 SPECIFIED CONTINUE
1 3 7 1 0.0 1 1.0e-5 1.0e-5 200 GMRES

Question:
Which NWT print flag/setting (e.g., IPRNWT, solver option, debug/extended print) forces MODFLOW-NWT to write that detailed table? If it’s no longer printed by default, is there a known workaround/utility to generate the same table for SWAT-MODFLOW?

I can share NWT/OUT snippets if helpful. Thanks!
