Global Variable

The Global Variable statistics record the time evolution of each global variable in the system. This data is written to GlobalVariables.txt as a time series, where each column corresponds to a defined global variable and each row represents a simulation time. The output file is updated at the Statistics Output Write Interval.

Note

If a Moving Parametric geometry is attached to a global variable, the position of the body center is written to a separate output file named GlobalVariable_{DynamicName}.txt, where the dynamic name corresponds to the name of the global variable in the Model Tree.

Statistics Table

The index table below shows the statistics that can appear in the Global Variable output file. Within this table, each statistic corresponds to a column in the output table that evolves with the time column. A separate column is created for each global variable defined.

Usage and Interpretation

Global Variable statistics are used to track the time evolution of all global variables. Users can monitor custom variables throughout the simulation and verify that they evolve as expected. This output is useful for extracting time-series data for analysis or post-processing.
