Visualizing Computational Fluid Dynamics
This tutorial shows common visualization techniques for cfd datasets. We will be using the dataset disk_out_ref.exo, found in Paraview under File/ Open/ Examples. It has a vector field in it called V.
Slices
- File → Open → Examples → disk_out_ref.exo.. On the Properties tab, click Apply.
- Filters → Common → Slice. Apply. Unselect the Show Plane.
- Color by: v.
- In the pipeline browser, select disk_out_ref.exo
- Filters → Common → Slice. Y Normal. Apply. Unselect the Show Plane.
- Color by: pres.
- View → Color Map Editor → Presets (the little envelope with a heart) → Turbo.
- Select disk_out_ref.exo in the Pipeline Browser. Turn on visibility (click on the eyeball to the left).
- In the Properties tab, (down a few pages), change Opacity to 0.4.

Stream Tracers - lines and tubes
- File → Open → Examples → disk_out_ref.exo.. On the Properties tab, click Apply.
- Filters → Common → Stream Tracer. v. Seed Type: Point Cloud. Uncheck Show Sphere. Apply.
- Color by: v.
Lines don't color as nicely as surfaces. Lets add a tube filter around each streamline.
- Filters → Search. Type Tube. Apply.
Now, we want to know which directions the particles are moving. We will use a glyph filter. Note we place the glyph filter on the streamline, not the tube.
- Select StreamTracer in the Pipeline Browser.
- Filters → Common → Glyph. Glyph Type: Cone. Orientation Array: v. Scale Array: v . Very Important - Scale Factor select the recycle button to the right. Apply.
- Color by: temp.
- View → Color Map Editor → Presets (the little envelope with a heart) → Black Body Radiation.
