# QHow within CFX-Post can one perform a circumferential average along a circular line of specified radius and at a specified height in a mixing vessel.AThere are two ways of doing this. One would be to create a Polyline by importing From File, and then use the lengthAve option in the Function Calculator.The other way, which does not involve creating a data file to import and which is done entirely within CFX-Post, is as follows:1. create a new Variable called RADIUS which is the radius (e.g. sqrt(X*X+Y*Y) if the circle is to lie in the X-Y plane)2. create a Plane on which the circle is to lie (e.g. the X-Y plane)3. now create a Contour and plot RADIUS on this plane4. create a Polyline using method From Contour, and choose the appropriate Contour Name (the contour created in 3.). Choose the Contour Level that you want5. use the Function Calculator to give lengthAve on Polyline 1 of the variable in which you are interested.
