Burner Example : result not matched
« on: May 05, 2015, 11:55:41 pm »

Hi!
I tried burnerfire example given http://www.thunderheadeng.net/pyrosim/docs/BurnerFireEx.pdf.
but thermocouple results obtained after running the simulation and given on above site are different.
The psm file is attached here. I am not getting why their is huge difference between temperatures. Please reply.

Hi Ankita,I made that exercise once, and I had got  a different result too. So I installed an older version of PyroSim 2012.01.0605 and I got approximately the same result as they show in this .pdf! (Look at the attachments). I think the Thunderhead Eng team, should update those exercises to be applied  to the newer version of PyroSim! I hope I help you!

Hi Wilson!
Thank you for your reply. But still i am confused that which result is reliable, Older one (version-2012) or the newer one (version-2015).

FDS is always improving, that is why they are releasing new versions.  If I had to trust one 'more' than the other, I would go with the most recent version of FDS available.
