Postprocessing
I have a circular cyinder in axial flow and I'm calculating the temp. and heat transfer coeff. on the cylinder walls. After the simulation I export result files with the coordinates, temp, yplus and heat transfer coefficient because I want to plot them, but I only want to plot from the middle of the cylinder front, across the circumference to the middle of the backside of the cylinder, so I need values in a straight line. Until now I've been using matlab so I can sort the different nodes and interpolating them in a straight line but I wonder if CFX post can give me the results right away in a straight line or if CFX post itself can make a graph with what I want!!! Any ideas or suggestions anyone?

Re: Postprocessing
Define a text file containing:
- the number of points - the x y z -coordinates For example: 4 1 1 1 2 1 1 3 1 1 4 1 1 Read in the polyline. Export the variables you want on the polyline. The polyline does not have to be a line. It can be just a bunch of random numbers. Astrid |

Well....I don't want to seem too stupid but I didn't quite follow you...can you perhaps explain one more time?

Hi Dimitris,
Create a Plane in Post which cuts through your cylinder. Then create a Polyline by intersecting the cylinder boundary and the plane. You can then create a graph using the polyline you have created and the variable you wish to plot. Alternatively, you could export the data from the polyline to a file and plot it in the application of your choice. Robin |

You're not the first one with this kind of problem. You might take a look at this link:
