Default PLotting iso-surface in 3D

I've got a "tube" in a half 3D configuration.

I would like to plot the velocity in the symetry plane (x-y), for a given X (vertical iso, at the end of the tube) to see the speed close and far from the tube.

But I don't know how to plot it just in the symetry plane... http://img92.imageshack.us/img92/7622/tubeuo7.png

Can anybody help me !!??

Many Thanks !

(I tryed to create an iso surface x=1,50m, and plot it like in 2D, but it does not work)

The reason of this plot is that I want to see how far from the tube the turbulences become low (to check if my wings (that's a small rocket) are wide enough to get out of the turbulences area).

Many thks !!

Open surface->iso-surface. Choose "Grid..." from the first drop down panel and "x-coordiante" from the second drop down panel. Click "compute" to get the min/max values for x. Input the desired x-value in the iso-value line and click "create". This will create a new surface for postprocessing (display->contours ...).

Thanks, but when I do this, Ive got a plane like this one : http://img141.imageshack.us/img141/27/tubetr1.png

And the result is not very good (very bad in fact) : http://img215.imageshack.us/img215/5...eresultgd7.png

What I want is to plot it only in the sym plane, like a 2D case...

Do you know how ??

For xy plots you can use a line for postprocessing. The follwing picture shows a 3d nozzle an how create a line (surface->line/rake) aligned with the green area.

And here is the resulting line and the velocity plot along this line.

Hope it helps, RoM.
