Hello,

I have modelled a building with an atrium. The aim of the model is to produce smoke which rises above the atrium, but there are a few errors with my modelling on Pyrosim.

I've attached the FDS coding for this.

How do I move the OPEN VENTs to the mesh boundaries?

Hello,

I have just modelled a building containing an atrium which is meant to generate smoke when viewed in SmokeView. I just opened Pyrosim and SmokeView, but nothing appears.

I've attached a screenshot of the model in Pyrosim.

Does anybody know what this means?

Hi everyone!
i have some problem when importing a particular .dwg file in Pathfinder. I can't see all the lines that i have in the dwg, and the lines i see are in the wrong place, in some cases.
I tried to change Autocad version in saving the file, and also to pass from .dwg to .dxf, without changes. I tried with other dwg and everything is ok, so i think it is a probelm of the file.
Can you suggest me something else to solve the problem?
Thank you! :)

How big is your burner going to be?

HRRPUA = HRR per unit area

HRRPUA = 2500 kW / area of the burner

Hello,

I'm modelling a building with an atrium. The atrium is 12m in length, 15m in width, and 9m in height. Height of each floor is 3m. There are 1.6 m wide walkways around the atrium at 3m and 6m high levels.

The fire needs to be medium-type of 2.5Mw (2500Kw), how would you calculate the HRRPUA ,please?

Okay, thanks for letting me know.

Under "Edit Reaction" there is a tab "Byproducts" where you can set the soot yield.
Obviously you need to choose a reaction first.

I have created little volumes of particle clouds (massless tracer) in front of each HVAC vents (17 in total). Works beautifully, just like tracer from supply vents. It seems to be doing the same job. Thanks again!

Thank you Bryan, very helpful!

It gave me a great idea!!

I will submit it on fds issue, too.

I am trying to model a room fire in Pyrosim and want to change the soot yield.

Does anybody know how to set a soot yield to 0.2 kg/kg?


Thanks,

Robert
