Cleaning up NX Flow image


NX6
I did a sample file, which consists of a wing element, an end plate, and a pylon,
plus a large box of "air" around it all. Now I'm looking at the results, and there
is a lot of info away from the wing, that I'd like to not see...I'd like to see
just the pressures, and velocities on the wing/endplate/pylon surfaces.
I used the Fluid Domain method to mesh the block of air, with a plane of symmetry
on the centerline face, the bottom is a smooth surface, and all other sides are
open. I let the solver find the wing/endplate/pylon on it's own, rather than specifically
pick them as Flow Blockage.
Is is it possible to get data displayed for just the wing surfaces? I've been hunting
thru the Docs, and CAST, but have not found it yet. I've also been trying to get
"streamlines", and have not muddled thru that to get those yet either.

Dave,
Velocities are (by definition) zero at the surface, so you won't be able to display
these without the fluid elements.
You can request Surface Pressure output on the Edit Solution, Results Options tab
under 3D Flow. This will generate surface pressure results on the non fluid elements.
To create streamlines, generate a post display of velocity, fluid pressure, etc.
with the fluid elements displayed. Then right click on the Viewports, Fringe Plots,
Post View item on the Post Processing Navigator and select Create Streamlines. Create
a seed set, then OK out of all of the forms to get the streamline display.

Thanks, that helps a lot!! It would still be nice if you could turn off the elements
on the fluid, so you can see the results better. Also, if you could make the results
translucent, so you could get a better 3D image of whats going on, when in the shaded/banded
type views.

Dave,
You can make the results translucent.
First, you will have to turn on global translucency support.
- Pick Preferences, Visualization
- On the Visual tab, toggle on Translucency
Now, to make the results translucent, pick Post View (the camera icon)
- On the Edges & Faces tab, set the primary display faces to translucent
You may also want to experiment with the cutting plane. This is on the Post View
display tab. Set Display On to Cutting Plane and use the Options button to define/move
the plane.
Regards,
Jim

Jim,
Thanks again, I'll give this a try...you've been much more helpful than the docs.
