Hey - yeah. This was my ultimate choice. Initially I put in a slab with really high fictitious density in the middle of my shield (to allow stuff to scatter back and around to the dose location), but ran a test case and imp=0 was way faster and almost identical results.
if there is no shield...
Hello - what is an accepted definition of the skyshinne dose in MCNP and how would you calculate this? If you have a source and a shield a few meters away between the dose point, the contribution that goes around the shield would be skyshine....but..what if you have a big source region (e.g., a...
thanks - .m file is the MCTAL file (obviously! :) )...one day when LANL makes this a user-friendly code it will transform it from formula one to bentley
Hey Alex - so yes, F15, F25....can be used separately but this option allows you to use F15 and then list multiple detector locations (not ring or a sum...the results appear to be as if you separately assigned a tally number to each). Discussion in the manual is limited, but in latest manual...
The MCNP manual states that you can have multiple detectors for a single F5 tally. Say you have f15:n x1 y1 z1 r x2 y2 z2 r.....Thing is, my output file only lists the tally result for the first f5 detector (x1,y1,z1). Where are other detectors for this tally? Is there a reason code developers...
