主题: source.f question
Dear FLUKA experts,I 'd like to ask your a question,[X][X] i want to sample the coordinates of the source particle in ring cylinder,the radius from 0.5cm to 0.6cm, the height is 0.45cm.and the source is isotropy，how i set the
Particle coordinates and Cosines (tx,ty,tz) in the source.f 。
the second question sample the coordinates of the source particle in cylindrical surface, the radius is 0.5cm,the height is 0.45cm.
the third question is can your explain this statement.
ZENMAX = PIPIPI
AZI = TWOTWO * PIPIPI * (FLRNDM(dummy))
CZMAX = COS(ZENMAX)
CZEN = FLRNDM(dummy) * (ONEONE - CZMAX) + CZMAX
SZEN = SQRT((ONEONE - CZEN)*(ONEONE + CZEN))
TXFLK (NPFLKA) = SZEN * COS(AZI)
TYFLK (NPFLKA) = SZEN*SIN(AZI)
TZFLK (NPFLKA) = - CZEN
thank you very much.
