Default Pressure coefficient

Hello to all,

I have studied, with Fluent, the problem of flow past a circular cylinder in a uniform stream and I have plotted in XY graphics the pressure coefficient vs position(m). I have obtained two curves, one for the upper surface and one another for the lower surface!

The questions are:

1) The direction of the pressure coefficient is orthogonal to the cylinder surface?

2) How can I plot the pressure coefficient distribution only for the upper surface and only for the lower surface, in two separate graphics?

3) How can I plot, in Fluent, the pressure coefficient vs angle?

Thanks a lot

You can create an Iso-clip located on the cylinder wall and with visibility criteria of y>=0 if you want to plot only for positive y
Also, I've tried to plot Cp x theta but haven't found any help on that, so I'm taking that it's not possible to do that on Ansys. I'm using Excel to transform from Cartesian to cylindrical coordinates...
