主题: Re: [fluka-discuss]: EMFCUT problems about what(3)
Dear Yang,
could you possibly send your input file — or a minimal version of it — to reproduce the issue?
Thanks, luigi

Dear fluka users,
Recently, I meet a strange thing about the EMFCUT card, I run an input file in the new version fluka, it gives the error message as follows:
*** Atomic electron contribution to mcs for material 3(HYDROGEN) set to 0, are you sure? ***
*** if so re-enter it as 1.E-05 and run again, if not check the manual for the ***
*** EMFCUT card, PROD-CUT, what(3), execution stopped meanwhile ***
Then I check the relevant card:
EMFCUT -1E-05 1.0E-5 BLCKHOLE _at_LASTMAT PROD-CUT
EMFCUT -0.0001 1.0E-5 bh _at_LASTREG
EMFCUT -0.0005 2.0E-5 pole1 xshuigd8
EMFCUT -1E-06 1.0E-7 detector detector
The strange thing is that the input file can be successfully ran on the old version FLUKA and it has no problem. I guess it may be related to the upgrade of the new version FLUKA, I read the manual, is says:
WHAT(3) = FUDGEM parameter. This parameter takes into account the
contribution of atomic electrons to multiple scattering. For
production and transport cutoffs larger than 100 keV it must be
set = 1.0, while in the keV region it must be set = 0.0
Default: 0.0
I think the problem is the cutoff energy I set,i.e., 1e-4,5e-4 is larger than 100keV. So then I add What(3) of EMFCUT card as follows:
* ..+....1....+....2....+....3....+....4....+....5....+....6....+....7....+....8
EMFCUT -1E-05 1.0E-5 BLCKHOLE _at_LASTMAT PROD-CUT
EMFCUT -0.0001 1.0E-5 1.0 bh _at_LASTREG
EMFCUT -0.0005 2.0E-5 1.0 pole1 xshuigd8
EMFCUT -1E-06 1.0E-7 detector detector
Unfortunately, I still get an error as follows:
Setting EMF leading particle biasing with What(3) of EMFCUT is deprecated!
If you really want EMF leading particle biasing use the EMF-BIAS card instead.
I don't know why. And I don't know why it can be run on the old version FLUKA and the current free-installation version(flupix-2011.2c-6_flair-2.3-1_x86_64.iso).
Could anyone help me to point out what's wrong with my input file? Thanks!
Best regards!
