FLUGG input
When transposing a fluka input in a flugg input you need to:
a) Update the following fluka cards substituting fluka region indexes with G4 geometry volume indexes: (in parenthesis the WHAT() with region numbers):
ASSIGNMAT (2,3,4) BEAMPOS (6) BIASING (4,5,6) DETECT (6; contin.card:2-6) EMF-BIAS (4,5,6) EMFCUT (4,5,6) EMFRAY (2,3,4) EXPTRANS (3,4,5) GEOBEGIN/END no WHAT exept COMBINAT; throw away everything between GEOBEGIN/END GLOBAL (1) LOW-BIAS (4,5,6) LOW-DOWN (4,5,6) RESNUCLEI (5,6) STEPSIZE (3,4,5) TIMECUT (5,6) USRBDX (4,5) USRBIN (4,5,6; contin.card:1,2,3,4,5,6) USRCOLL (4) USRTRACK (4) USRYIELD (4,5) WW-FACTO (4,5,6)
b)integrate the following material cards with information: DELTARAY, EMF-BIAS, EMF-CUT, EMF-FIX, EMF-FLUO, EVXTEST, FLUKAFIX, LAM-BIAS, LANDAU, LOW-MAT, MAT-PROP, MULSOPT, OPT-PROP, PAIRBREM, PHOTONUC
When comparing fluka and FLUGG runs, REMEMBER to: 1) check that coordinate system is the same in fluka geometry and in GEANT4 geometry; if it is not, update position and beam direction.
