In the Macro Calculator, the Macro setting has a drop-down list that lists the available macros.
Some macros are predefined and are already in the list of available macros. Other macros (user-defined macros) can be added to the list of available macros in any of the following ways:
In the Macro Calculator, click Browse and select the macro file (a CFD-Post session file with extension .cse). This will make the macro available for only the current session of CFD-Post.
Add the pathname of your macro file (which has the file extension .cse) to environment variable
CFXPOST_USER_MACROS
, which is a comma-separated list of the pathnames of your macro files.
