GLOBAL GEOBEGIN Moreover there is the possibility to export to other Monte Carlo simulations programs like MCNP X 14 15 MARS 16 and various plotting formats FLAIR takes care to reorganize the input file before saving to disk by moving all the special cards in the appropriate position in order to have a correct FLUKA input file The reorganization of the input file taking into account all the preprocessor cards that might alter the flow of the input file in case they are displaced Therefore FLAIR will try to move or clone the preprocessor cards in order to create a logically correct input file All FLUKA cards in FLAIR are described by the extended input card to have a uniform treatment Each extended card is composed by e comment lines the ones preceding the card definition as well the in line comments e atag which corresponds to the FLUKA card name With a few additions regions are defined with the REGION card All preprocessor cards have tag names like define undef 1if e a variable number of whats Starting from what O which corresponds to the sdum what 1 what 6 are the same with the FLUKA whats what 7 what 12 correspond to the what 1 what 6 of the first continuation line etc e Some cards carry additional information which is accessible as what 1 It is used also to store long strings or multi line information used by some cards like TITLE GEOBEGIN PLOTGEOM or REGION e state of the card can be ei2. ep z 100 Drz POSITIVE v GEOBEGIN Applicatio ni oe iJ Developers Tite N_TOF lead target _jPreprocessor Process Each body Debug SPH 8LKBODY x 0 0 Compile R 10000000 0 Run Void sph Files SPH VOID x 0 0 R 1000000 0 Usrcoll Water contar RPP WATERC NT X 43 0 mx 43 0 53 6 max 53 6 32 5 Zmax 35 0 Lead Target RPP PBTARGET xm 40 0 Xmax 40 0 vm 40 0 Ymax 40 0 Zmin 30 0 Zmax 30 0 ooo Nu WE min 1S n os LASLA define A characteristics properties of prinarg particle 1 4 6 7 BEAK 20 0 0 082425 1 7 1 OPROTON E Exe Dir fhome onv prg physics Nuka Nairfexamples Filtered 37 out of 37 Figure 1 FLAIR main application window The input editor provides also means of filtering the cards in order to reduce the number of visible cards in the display or to group cards that are related by a specific property By selecting the appropriate category or manually creating filters FLAIR displays only the relevant cards and hides all the unwanted ones One important feature of FLAIR is the filtering of linked cards by a single click of the mouse the user can display only the cards that are linked by a specific property e g the same material name or region etc Higher level filters can be created by a specialized dialog permitting the user to create a filter based on a combination of rules and allowable ranges for various types During the setting up of a simulation calculation the
