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

Hello,

This is not possible at this time, it is a limitation of FDS in how we cannot specify particles to source from our recirculate through HVAC vents/systems. I would recommend that you add a feature request for this to the FDS Issue Tracker. https://github.com/firemodels/fds/issues/new

If you are looking to trace the movement of gasses within a room/volume, then you could just add a particle cloud source for the room volume.  Make sure to set the age of the particles such that they move around for the duration you are interested in.

Read chapter 18 of the FDS user guide.

Hi,

It does not seem possible to have a massless tracer for a new gas species. Works with water vapor but not with a custom species (NCl3, for example). Mass flux is specified (not mass fraction). Nevertheless, no results. Is there a special trick to know about?

thanks,

Helene

Hello,
Is it possible to have massless tracer when using HVAC network? Can not find how to. For supply vents no problem.

thanks

At the least, you are going to need to post your file in .psm or .fds format.  It seems that there is an issue with the geometry of your model, but it is impossible to tell from commentary alone.

I am running a model in Pyrosim, but it won't simulate. the following error message appears: 'Could not load results. File does not exist: C/Program Files/Pyrosim2018\/fds/objects.svo

Can anyone help?

Dear all!

I have a project where we are using the latest version of Pyrosim.

When finished simulating and trying to view the smoke produced by the fire, the smoke from the fire starts to travel up just a little bit(approx 2 metres), and then spreads horizontially and not touching the roof.

Does anyone know how to solve this issue?

Just for the record, once the smoke has filled the room with smoke at a height of approx 2 metres, THEN the rest of the smoke starts proceeding up to the roof..

Best regards

Yes, I understand. Thank you. I will read the relevant sections of the Pyrosim guide to help me. To answer your question, it is for an assignment.
