Hi,
The direction of the flow can easily be derived from the filling pattern though. A nice way to do this is by overlaying the Orientation at Skin plot with the Fill time plot (which is actually what the Orientation at Skin plot is derived from).
To do this, first display the 'Orientation at skin' result and then Right click on the 'Fill time' result and select 'overlay'. To improve on this a little more, you can Right click on fill time plot once more, select 'properties' and the select ‘contour' as a display option. This will display the fill time plot as a contour plot. You can choose to increase the number of contours to get a little more detailed information to what is happening locally in critical areas.
I hope this helps
