Hi Daniele,
Thanks! I believe I’ve solved it by setting the NY of several PLA to 0 instead of 1E-17 and by coinciding several planes. It can run on both Flair3.4/Fluka4.5.1 and on Flair2.3/Fluka2025.1. However on a cluster it still fails with segmentation fault (“Seed file not accepted: or corrupted…” and “2 Segmentation fault (core dumped) ${EXE} 2> $LOGF > $LOGF fluka run”).
I attach my final input if ever you want to check. Thanks!
