Dear FLUKA users and authors:
I am trying to run my own input with FLUKA and I have ran into a problem. When the program finishes running the input, it stops at the GEOBEGIN option card and prints out this message in the .out file.
Unknown input card!!!!!!!!!!!!
The program reads everything up to the end of the BEAMPOS card and from what I can tell, it does not recognize the GEOBEGIN card. I have tried many things to get this to work but nothing has worked. If anyone could point out the error in the following input file, it would be greatly appreciated.
