Size of puffs
Posted: October 9th, 2019, 10:20 am
Hello
I have been making visualizations of particle dispersions. I'd like to try making visualizations of puffs as well. In the PARDUMP file, where is the information on the size of the puff? Such as radius? I would think that SIGW, SIGH, and SIGV would be the radii across x,y, and z directions, but these numbers always seem to range between -0.5 and 2, and don't significantly change over time. How can these numbers be negative? Any explanation is very appreciated!
