Dear all,
Hi. Hope are well. I wanted to ask how can I make variable of temperature that gives me an average of temperature in all cross sections of a domain so that I can plot that temperature versus the axis of a pipe? I know that an expression can be used in making a scalar varaiable. I made an expression "areaAve(Temperature)@Plane X" but that only gave me average temperature at one plane. I want to know how can I plot for example inner pipe and outer pipe/annnulus average cross sectional temperatures versus axis of pipe. Basically I have found out temperature along a line versus axis of pipe. I did that by making a line but I want to know how can I extend that concept to all cross sections in a domain? Would be extremely grateful. Thanks. Last edited by Shomaz ul Haq; March 15, 2016 at 05:30. |

The only way I can think of to do this is to generate lots of cross sections. You can make this easier by scripting it using a session file in CFD-Post.

Thanks a lot Glenn. What is a "session file" and "script"? and how can I script using a session file in CFD Post? Would be grateful. Thank you.

Have a look at the documentation for CFD-Post. It describes session files.

Hi. Hope all are well. Thanks a lot Glenn. I looked at the CFD-Post Session Menu in ANSYS Help. It tells how to create a new session command, start recording and stop recording, and play session command. I am confused how to generate graphs of average values of variables in a domain at different cross sections as I want to plot average variables values along the length of pipe. I don't know anything about scripting. Can somebody help? I need it urgently. Is there a tutorial online where I can learn this? Would be extremely grateful if you could help me out. Thank you.

Hi all. I have understood what is a script file, process of scripting, saving and recording it. Now I want to ask what is meant by "scripting a session file" as by definition scripting is the editing and running of "journal files" and how can I do that to create average values of variables in a domain at different cross sections along the length of a pipe? Would be extremely grateful if someone could help. Thank you.

Have a look at the power syntax (using perl). Then you can put loops, conditional statements, maths and other features in your session files.
In your case you could create a loop which generates lots of cross sections, then gets the averaged condition at each cross section and outputs it to a file. |

Yes, you can define the sections in the mesh and do it in the solver and output the results to monitor points.
