Screen simulation

solids -> oversize + undersize (PSD cut)

Governing equations

The exact equations the solver works for a screen — the same math shown in the app's "Theory" panel, not a black box.

$F_{under}$

fraction of feed reporting to the undersize stream [0..1]

$\Phi$

standard normal cumulative distribution function

$c$

screen cut size (aperture) [m]

$d_{50}$

median particle size of the feed [m]

$\sigma_g$

geometric standard deviation of the log-normal size distribution — how wide the feed's size spread is

Parameters

cut_size_m [m, required]; the feed PSD (mean_size_m, gsd) rides on the solid stream's solids payload from upstream
