Dear Andrea,

Can you send me a screenshot with this error you found? I have nor error or warning when I open my input so is hard to fix it.
Thank you for your advices!


Regards,

Roxana

Roxana,

I opened up your input file in flair and noticed that it has some geometry
errors at x-layer 30 around the thin walls on the right, interior side.
Also, if you are having trouble with positioning the beam, it can be
helpful to do a single run with a small number of particles with your
USRBIN card set to detect BEAMPART. That should allow you to visualize the
changes to your BEAMPOS card.

Best of luck,

Andrea
