output of volume flow rate at louvred vent #1074

Closed gforney closed 9 years ago

gforney commented 9 years ago
Please complete the following lines...

Application Version:5.4.1
SVN Revision Number:
Compile Date:
Operating System:win-xp

Describe details of the issue below:
I have found that the output of the volume flow rate is about 20% 
higher than my actually input volume flow rate. 
I think there is an error when calculating an angled supply in the 
output part. 

Input file: 

&SURF ID='INVENT1', VOLUME_FLUX=-0.7, VEL_T=0,-8.0 
&VENT XB=14,14, 2.8,3.0, 11.2,11.4, SURF_ID='INVENT1' / 

&DEVC XB=14,14, 2.8,3.0, 11.2,11.4, QUANTITY='VOLUME 
FLOW',ID='INVENT1'/ 

My input is 0.7m3/s, the actual output in devc.csv file is 0.843 m3/s. 
This is misleading.

run your case with the latest version of FDS and if it still does not do what you
think it should attach the simplest version of a complete input file that reproduces
the problem.
