Pressure distribution over a curve in CFX-Post
 

I am simulating a flow over a cylinder. I need to create a chart to find out the pressure distribution along the surface of the cylinder. The problem is how do I have an angle from 0 to 360 degrees on the x-axis ????

I need to know what I should be taking in my x-axis ???

You can define this as a CEL expression, something like

angle = atn((y-y_centre)/(x-x_centre))

I can't remember whether it is ATN or ATAN, you can look that up. Then you can use the value of this variable on the surface as the X axis for your chart.
