GfsOutputScalarHistogram

From Gerris

GfsOutputScalarHistogram computes a histogram (i.e. a discretised probability density function) for a scalar field.

The syntax in parameter files is:

[ GfsOutputScalar ] { n = 100 w = [ GfsFunction ] }

with

n

number of "bins",

w

an optional weight to apply to each sample. The default is the volume of the cell.

The resulting file will contain two columns with one line per bin. The first columns contains the frequency and the second the value.

If a step or istep parameter is specified in the parent GfsEvent, the histogram is time-averaged.
