Consider a rotating propeller in a fluid. The propeller is rotating in relation to a fixed coordinate system in the fluid domain.
If you freeze time and slice the propeller blade airfoil with a plane, the velocity field in that plane would look something like case on case 1, on the picture below.
If you instead have a coordinate system that is fixed in relation to the propeller blade and freeze time, you would instead see the something like on case 2.
So my question is:
How can I visualize the flow like in case 2?
I have downloaded paraview, I guess it would be good to do it in that software.
