Particle Screen

Particle Screen statistics are written to tab-separated ASCII .txt files that record time-evolving raw and reduced quantities associated with particle–screen intersection events. This output reduces the spatially resolved particle screen VTK visualization outputs to a simple set of descriptive statistics A unique output file is created for each screen, which reduces data from all particle families. The name of each output file is ParticleScreen{Axis}_{Intercept}.txt, where Axis and Intercept correspond to the Axis Direction and Intercept Value.

The data is written as a time series, where each row corresponds to a simulation time and each column corresponds to a statistic listed in the table below. Each row in the output file corresponds to a new statistics output time and is appended at the Statistics Output Write Interval.

Statistics	Units	Details	When Appears
Time	s	simulation time
Count	Dimensionless	number of particles not including number scale
Density COV	Dimensionless	spatial COV of particle density not including number scale
Density Mean	number/mm^2	spatial mean of particle density not including number scale
Density Std Dev	number/mm^2	spatial standard deviation of particle density not including number scale
