Dear Fluka experts,
UPDATE - I believe the issue described below actually has to do with the number of points in the USRBIN which I defined. If I scroll up from the error messages which I showed in the screenshots below, Flair seems to complain about a dimensionality issue - the grid has too many points. My grid has 350^3 points. Is there a way to rebin the USRBIN output so that the array dimensions are not too large to be plotted? If so, how would I go about doing this? It would be nice to rebin the data I already have and not have to re-run the simulation.
I am having trouble plotting an output from my simulation. I tried to score neutrons in a region of interest. When I try to make a 2D heatmap with the .bnn output in Flair, I get this error.
I see that the error states “No usable data in this plot to autoscale axis range” and “All x points undefined”. Why would I get this type of error? I also scored neutrons using the USRBDX card in smaller regions and obtained sensible outputs. Please advise.
Thanks in advance for any insight,
