Output Surface¶
The Output Surface statistics provide time-evolving, raw and reduced descriptive statistics evaluated over the output surface. For each enabled variable, the solver reports surface-based minimum, mean, and maximum values, as well as integrated surface quantities where applicable, such as total area and volumetric flux. This output produces a tab-separated ASCII .txt file named OutputSurface_{DynamicName}.txt, where the dynamic name corresponds to the name of the Output Surface in the Model Tree.
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.
