Mulmix.f Fortran runtime error

Dear FLUKA experts,

I ran into an error with cascade/mulmix.f when I was running an input deck. In my .log file I got

At line 391 of file cascade/mulmix.f
Fortran runtime error: Index '0' of dimension 1 of array 'fclmbz' below lower bound of 1

Error termination. Backtrace:

I am not sure what it means or how to debug. How do I solve this issue?

Here is my .inp and output files
FB3_design.inp (66.3 KB)
FB3_design.log (578 Bytes)
FB3_design.out (339.7 KB)

my fluka version is 4-3.4

Thank you!

Dear Kali,

you are missing the COMPOUND card for the CERNSS material.

Cheers,
David

Dear David,

Thank you! I added the compound card for CERNSS and the simulation is running.

Cheers,
