Can /sci/ help me ?

Is there an easy application that generates vector field maps from Navier-Strokes simulations ? It usually represents directions and velocity with colors.

I'll post a few examples

They are outputted as 2D maps. Another example

I use PARAVIEW for this.

It's FOSS but you might have to do some surgery on your export setting or file format

Both use the VTK (The Visualization ToolKit) library.

Both are excellent but I'd go more with VisIt.
If I recall correctly PARAVIEW is bundled with OpenFOAM.

I used Fluent, with mesh generated using Gambit.
It is quite nice
