statistics

The statistics module is used to analyze the statistical distribution of a field with nodal data. The data field can contain any number of data components. Statistical analyses can only be performed on scalar nodal data components. An error occurs if a statistical analysis is attempted on vector data. Output from the statistics module appears in the EVS Information Window. Output consist of calculated min and max values, the mean and standard deviation of the data set, the distribution of the data set, and the coordinate extents of the model.

The first port (the leftmost one) should contain a mesh with nodal data. If no nodal data is present, statistics will only report the extents and centroid of your mesh. Data sent to the statistics module for analysis will reflect any data transformation or manipulation performed in the upstream modules. Any mesh data sent to the port is used for calculating the X, Y and Z coordinate ranges. The mesh coordinates have no affect on the data distribution. Cell based data is not used.
