Another Vorticity Advection Map

Here is another way of displaying vorticity advection. For this product we will use the CTFC (Fill Based Selected Color) command to display the vorticity advection.

Copy the following code and paste into your favorite text editor. Save the file as CFCO.DAT in your WINGRIDDS/USER directory.

You will more than likely have to make some edits to the macro to account for your color palette setup.

That's it for this one enjoy!
