Dear Jonathan,
If you are interested in the produced residual nuclei, USDRAW is not the right place to look. Instead you should use the USRRNC routine (activated via WHAT(5) of USERWEIG), where you can intercept all residuals as they are scored with RESNUCLEi. Among the arguments passed to USRRNC, you can for example find Z,A, the region number, and the position.
While USRRNC is called when the residual nucleus is scored, USDRAW is called at the level of interactions (e.g. there can be cases, where residual nuclei can appear on the stack and IBRES and ICRES are not filled; there are also other cases, like fission, where products do not appear in IBRES and ICRES, see
http://www.fluka.org/web_archive/earchive/new-fluka-discuss/3948.html).
Cheers, Anton

Subject: [fluka-discuss]: (RESNUC) and USDRAWþ
Hello dear Fluka users,
I want to get the residual nuclei produced in a Iron target bombarded by 230 MeV neutron using USDRAW. I used Icres and Ibres from RESNUC with several mix of ICODE (with all event, without elastic scattering or without photon event) and I never succeeded in reaching the concentration of residual nuclei given by RESNUCLEi card. I tried to include Flaevp(m) and Flzevp(m) but again no matching between my usercode and RENUCLEi card. I really don't know how to mix these variables to get the same concentration than RESNUCLEi card. How am I supposed to do that?
Thank you very much,
Best regards,
Jonathan Derrien
PS: I am sorry for the previous mail, I made a mistake and so my question was in the reply of the previous question.
