Circumferential Average of Data

MissCFD · May 22, 2015, 23:17

Hello,

I would like to do a circumferential average of my data located on a plane.
Let me explain: for a given radius, I would like to do the circumferential average of the radial velocity for example.

I used Tools $\rightarrow$ Radial Internal Table but I'm not sure that it's the good way to do this because I don't think that an average is done with this method and moreover I don't know where the data are taken on my plane ...

Can somebody help me ? Could I plot a line on the radius contour of my plane and do an average of data on this line and repeat this method for each line of radius contour ?

Thank you very much

I find, I did a isosurface number (200 isosurfaces = 200 radius) of the radial position on my interest plane but now I do not see how I can extract data for on isosurface one at a time ... ? I don't see how I can do the macro !
Does anyone knows how I can do a java macro to change the number of interest isosurface and calcul and report the average value obtained on a radius out to a file ?

I could be off base with this, but I would create a series of probes distributed at the radius you want.

If you are looking for surface averages and not point data you could maybe create a derived part > cylinder section although this will create a surface extending thorugh the whole input part.

Its hard to visualize what you are wanting, perhaps a sketch would help if this is not what you were after?
