Hi Vladimir
Just two observations:
when setting extended sources with the BEAM card, please have a look at
the manual Note 4
4) All options governed by WHAT(3,4,5) are meaningful only if the beam
direction is along the positive z axis, unless a command BEAMAXES is
issued to establish a beam reference frame different from the
geometry frame (see command BEAMAXES). If the beam is not in the
positive z direction and no BEAMAXES command has been given,
WHAT(3)-WHAT(5) must be set = 0.0 (unpredictable effects would arise
Furthermore, in your source.f you are setting your beam spot to
(36.,58,.-57), while later you are not using it for x and y
XFLK (NPFLKA) = RADIUS * SFE
YFLK (NPFLKA) = RADIUS * CFE
In order to display your source, I suggest to put a fluence USRBIN around
the beam spot (or even entire geometry) and inspect where beam particles
go..
Cheers
Stefan
