Hi all,  
how to plot the pressure curves in functions of the angle (0 to 360) over a cylinder. the study is a numerical simulation of a turbulent flow around four cylinders in square configuration, I used _ **Gmsh** _ for geometry and mesh generation , then _ **Code\_Saturne** _ for the calculation.

You will have to compute the angle first. Could you do that befoehand ?

in the solver or in ParaView ?

in your solver.

This should be doable in ParaView, but will require some computation and knowledge about the cylinder that you must already have in your solver.
