In CFD-Post v12.1 you can insert a Vortex Core Region which is what your after, check it out in the User Guide.

And seriously, what are you doing putting a post on a forum on Christmas day if your request is urgent? If you have an urgent request then use CFX support. That is what you pay them for.
