Error processing USRBIN data

Dear Experts,

We are trying to design a head for a medical LINAC using FLUKA. Input file looks seems ok as it it runs successfully but it gives errors when we try to plot USRBIN output. Please find attached .inp file and screen images. Many thanks

The input file is attached. Any help please.

Kind regards,


Dear Saman,

there is no USRBIN card present in your input. The list of detectors in Flair sometimes don’t updates when a scoring type is changed or removed. You can use the left Remove button to delete the selected detectors, then use Scan to get the current ones.

Furthermore, it seems your beam starts after the geometry, or it is going in the wrong direction.
