[fluka-discuss]: Re: FLUKA: USRYIELD WHAT(1) = 3301 or 3299

Dear James,

The USRYIELD documentation says that

10) Not all 27x27 combinations of quantities are accepted by the code,
nor are they all meaningful (for instance one could run successfully by
setting WHAT(1) with ia = ie, but the result would have no physical
meaning).

I hope one day we will see all possible combinations in manual.

Try to use USRBDX card instead with user routine FLUSCW for various time
intervals.


Best regards,
Mikhail
