Particle count using transparent surface and issue with multiple core processors about sparta

[knstmrd]

I took a look at the input file – the issue is that if you run on more than one core, you can't rely on the ordering of the output lines.
So if you add additional surface info to the dump, for example element ID and one of the vertex Y-coordinates, like this
dump flux surf subs 200000 Sample_ParticleFlux_2.txt f_flux id v1y
you can see that the ordering depends on the number of cores you're running on.
So in the plotting/analysis you need use the coordinates that are being output into the file.

Thanks to your suggestion @knstmrd, I tried following your suggestion and it actually helped me understand and solve the issue. I am already able to produce the expected results that I need. I am also grateful to you @stanmoore1 for guiding me into this forum and on the SPARTA program.
