 October 16, 2002, 03:10 average value in any plane #1 Roy Chen Guest   Posts: n/a Hi~everyone i have a question about CFX see this pic(http://oz.nthu.edu.tw/~g903159/CFX/temp.jpg) i want to know the data of any plane for example: in X-Y plane,i want to know average temperature (not distribution) of each plane,along Z axle. so i can plot a XY average temperature vs Z graph can someone tell me how to do it? Best wishes Roy Chen

Just select the plane of interest and the value you want to know on that plane. You will find out that you can calculate a lot more than only the average value. Astrid

If you have many planes that you need to do this on then you should create a session file in CFX-Post for a single plane and the average, then go back and insert perl power syntax in the session file to create the other planes and averages that you need.

 October 22, 2002, 15:24 Re: average value in any plane #5 Neale Guest   Posts: n/a Hi Roy, You are using CFX-4. The answers that I gave you only apply to CFX-5. Perhaps there are some CFX-4 experts out there who can answer your question for you, or your support person (most likely the best approach). Neale.

I also saw that you have only 1 block. So, go back to BUILD and create a customized wall (under Create Patch 2D, e.g. WALL_1) and use the IPREC utility under the USRTRN subroutine. Inside this subroutine you can calculate the average temperate over the whole face of a block. Good luck, cfd guy
