CFD Post-Integration
 
Hello
I have a problem with CFD post processing, how can we do integration process ?
for example in we want to compute the bulk temperature of a fluid in a section we need to do the below integration. one method is to use function calculator
http://www.cfd-online.com/Forums/dat...AAAElFTkSuQmCC
the function calculator's ability seem insufficient in more complex problem like when it is desire to compute average Nuselt number in the section of a pipe
http://www.cfd-online.com/Forums/dat...BJRU5ErkJggg==,http://www.cfd-online.com/Forums/dat...AASUVORK5CYII=http://www.cfd-online.com/Forums/dat...BJRU5ErkJggg==Nu_loc=2r/k*(q_wall/(Twall-Tbulk))
Nu_avg=1/(2*pi)*int(Nu_loc,0,2*pi)

could anyone help me in this?
I cannot even do that in MATLAB due to unstructured mesh I used.
does anybody have any idea?

look into the CFX Expression Language (CEL).
there isn't anything we have not been able to do with this system.

If you need more complex, you can use the CCL and macro/session files to add perl programming.

You can also use the worksheet calculator to enter lots of more complex equations than the function calculator.

Sorry I am kind of beginner in CFX
I searched the index for the worksheet calculator but I got nothing
would you be so kind to explain more?

Have a look at the "table Viewer" tab at the bottom of the CFD-Post page.
