To run a macro (assuming that a case is already loaded):
From the menu bar, select Tools > Macro Calculator.
Select an appropriate macro from the drop-down list or open a CFD-Post session file that contains a user-defined macro definition. (In the latter case, opening the file both loads the macro into the Macro Calculator and adds that macro to the drop-down list.)
Fill in the settings that appear in the Macro Calculator.
These settings serve to provide input data to the macro. Which settings are required depends on which macro is selected.
Click Calculate to run the macro.
The macro might create objects, user variables, expressions, and other forms of output.
Some macros produce an HTML-formatted report that can be viewed by clicking the View Report button or by opening the Report Viewer.
