Dear Yao Yang,
as far as I know, you cannot specify the charge state of a heavy ion
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/6415.html
Concerning your problem of the transport of beam with a different change state in magnetic field, I slightly modified your magfld.f routine in order to avoid the compilation error.
Please find it attached and let us know if you still have problems.
Moreover, in your input file there is a STOP line before the end of the file: it means that everything after it (in your case a ROT-DEFI card) is not parsed.
Hope this could help.
Cheers, luigi

Hello FLUKA users,
I am trying to define a primary beam with heavy ions like uranium with a special charge state 34+. When I look through the FLUKA discuss archive, I found that the default primary particle in FLUKA is fully-ionized ion (for uranium is U92+). However, many different charge ions need to be transport in the accelerator. In FLUKA,the factor CHFACT=34/Zfrttk can used to transport of ions with 34+ (in this work), where Zfrttk is the actual Z_eff of the ion (smaller than Z) and stored in the COMMON 'TRACKR'.The factor was added in the magnetic field with editing magfld.f routine. I have complied my magfld.f file, and 'Invalid declaration of or reference to symbol'zfrttk''show in my output file. I attached my input file and magfld.f file below. Any suggeations or comments will be appreciated. Thank you very much in advance.
Best regards.
Yao Yang
