because of security issues. If you trust the code you can enable this
facility be adding to the InfoSwitches setting in the system controlDict:

The system controlDict is either

or
$WM_PROJECT_DIR/etc/controlDict

Greetings Mukesh,

Several months ago I explained how this can be done on the following wiki page: http://openfoamwiki.net/index.php/Ti...itional_tuning
