Its field inverse is the unbordered structure inverse; restricting an already scalar-bordered inverse could spuriously constrain the field solve. diff --git a/experiments/convergence_linear_cases_2026-09-19.json b/experiments/convergence_linear_cases_2026-09-19.json index bb2fa71..239a020 100644 --- a/experiments/convergence_linear_cases_2026-09-19.json +++ b/experiments/convergence_linear_cases_2026-09-19.json @@ -126,7 +126,8 @@ "--restart-snapshot", "../../diagnostics/coupled_convergence_2026-09-19/screen_v1/n2_J0/capture_3/physical_base.txt", "--allow-unconverged-restart", - "--no-central" + "--no-central", + "--benchmark-trials" ] }, {
