Dear Adrien,
You can set isotropic in BEAM card, without any SOURCE card. If you
really want to use SOURCE card, you must modify source.f user routine
and recompile FLUKA executable file with your new source.
Cosines for isotropic beam in source file:
* Cosines (tx,ty,tz)
CALL RACO( TXX, TYY, TZZ)
TXFLK (NPFLKA) = TXX
TYFLK (NPFLKA) = TYY
TZFLK (NPFLKA) = TZZ
ZFLK and TXFLK are not functions, but variables to Z-axis position and
X-axis cosine direction of the source particle.
Best regards,
Mikhail
