I would like to place two point sources at two locations to score dose eq at 1 m. As I understand that I can not use two BEAM POS cards, I have to use source.f file to give the two locations [(-50,0,0) & (50,0,0)]. I tried doing that, but I am not able to define the expression for FLRNDM(DUMMY). Please see the following:
Thank you David. I will try using SPECSOUR.
Can you please see the complete user routine attached and confirm the correctness, specially the particle co-ordinates?
Thanks in advance.

the attached source routine is for an older / incompatible version of FLUKA. Please try to use the current template located usually at /usr/local/fluka/scr/user/source.f, or use Flair to copy it to your project.
I tried using SPECSOUR and associated cards to define two Beam spots for Co-60 point sources. I got the results too…Thanks.
Referring to the slide no. 34 of the “Advanced source_2020.pdf”, how to define the length(or height) of the cylinder sources ? If it is a 2.5 mm cylindrical beam, I saw Rmax=0.25 (cm)…
In my case, it will be a (0.6 cm dia * 40 cm L) cylindrical sources arranged in either a circular or a rectangular array. Can I do this using Beam spots ?
I did once such evaluation using the source.f for defining the 25 cylindrical sources (0.6 cm dia. * 40 cm L).
Unfortunately, the Volumetric sources can’t be used with the multiple spot sources. To have multiple cylinders as your sources you need to use a source routine. (On slide 34 you see pencil beams with 0.25 cm radius.)
I would suggest to take a look at your colleague’s Jyoti Garg’s (@jyoti) problem, since she is using a similar source routine:
