I think when you split the face using iso-clip, the node values are used and as a results subsequent calculations may be not as accurate as you want. Chances are that even when you add up the areas of the neg. and pos. they won't give you the exact total area either. Maybe a finer mesh (adapt) can help reduce the difference.

I assume you are doing the split on a pre-defined face that you are also able to check the report --> flux, right?

AGAIN: When have I ever posted this comment? There may be afew times I have thought someone is just being lazy and decided to write this! I have made this point clear in most of my messages to you! On this actual thread I didn't start my messages with this, you should maybe look at my first post on this thread!!??

After asking advice from several friends on how to get you to just leave me alone - they told me to tell you where to go!, but I have decided to simply say that I will not respond again, and the above text is simply me repeating what I have already said!

Regarding my comments you keep bringing up, I was being sarcastic. You should look up the meaning on the web to better explain this. And in my opinion your behavior is worse than mines, as you have behaved in an arrogant manner, and if you look up the English language meaning of this also on the web or a dictionary you will see that I am correct.

So, to summarize, ok then yes I am immature, but you are arrogant, self righteous, intrusive and rude, as if you have no experience of fluent then you should not comment in the fluent forum and certainly not to someone who has helped(check my recent posts) so many people but maybe didn't indicate where in the documentation the answer was!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

No comments!

I also don't like to comment on this

Hi Barii,

You should have access to the Fluent OTS site. Under "Solution 522: Calculate massflow rate and maximum temperature at an interior face " the Fluent guys give a UDF to calculate the mass flow.

If this is a post-processing surface, then Bashu's comments above apply. One other workaround is to go back to your mesh and generate an interior boundary in gambit at the location where you need to monitor. This should help to get more accurate data out.

Thanks for your posting. The last time I has so much fun getting up to speed on the phil.osophy side of CFD was when John C. Chien was still a regular poster.
