Hello Team,

I am having issues in opening the PyroSim results files. Once the simulation is complete, the PyroSim result display opens. But when I select the Soot Density or the Temperature profiles t have a look at the results, nothing comes up. But the playbar is showing the correct time of the simulation (for eg. 0:00/30:00) in case of a simulation which has been done for 30 minutes. But there are no changes to the display.
But when I open the results through the smoke view by Analysis-Run Smoke View and open the results file, it is working fine. Can someone please help me in resolving this issue.

Thanks in advance.

Hello Team

I have been using Pathfinder for a while now. I recently updated the Pathfinder software to its latest version (i.e. 2020.3). Earlier, I was using its previous version (i.e. 2020.2) and I have created a few evacuation models using the 2020.2 version.
But after updating the software to its latest version 2020.3, I am not able top open any of the evacuation models that I created using its earlier version. And every time I try to open a file created using an earlier version, an error file appears at the folder containing the Pathfinder file. I have attached the error file with this message. It would be really great if anyone can help me in opening all the pathfinder models that were created using its earlier versions.

Thanks in advance.

I tried to do this as mentioned above, it doesn't work. Don't waste your time.I've been trying to get a job lately, but it's quite difficult nowadays. I was advised by a friend to improve my resume, as he says it looks boring. However, I'm don't want to pay $ 200 for a piece of paper, so I want to try writing by myself. I found a cool site https://copymyresume.com/, where you can find a lot of information about the resume. A variety of guides, resume samples, and so on. I've already learned a lot of interesting things. I hope I can do it!

Where can I find some more feedback?

Hi, I just setup a model for hotel lobby in Pathfinder.
Result film revealed that the wheel chair stand still and assigned occupant (assistant, white clothes woman) move around nearby but can't go to help him!
What's wrong in my pathfinder file?
Is there any step by step tutorial text about this new function?

Hello Everyone

When couple the results of pyrosim with pathfinder does Pyrosim results (Fire soot and heat) will affect on Pathfinder occupant’s decision making (Speed, Exit and Path)?

For example :
Occupants run away or exit from the building avoiding the fire
Or will the occupants run through the fire???

Hello Everyone,

I’m modeling a fire on a garment warehouse. Which is to be ignited spread and extinguished by sprinklers.
So is there any database or source available to get the properties or information (characteristics / details / composition etc.) that are necessary to input  in Pyrosim Reaction, Material and Surface dialog boxes.

For example:

Under Reaction Dialog Box
•   Fuel Composition of Garments
•   Energy Released of Garments

Under Reaction Dialog Box
•   Thermal Properties of Garments

Under Surface Dialog Box
•   Reaction of Garments

Please note that I’m totally new to this field.

It depends.

Restarting a simulation requires a .RESTART file for each mesh in the simulation. PyroSim has a default setting to have FDS write these files every 300 s (Analysis -> Simulation Parameter -> Output -> Restart). So, with the default setting, the simulation has to run for > 300s for a restart to be possible.  If the simulation runs for 599 s and dies due to a power failure, then it will restart at 300 s. If it runs to 601 s, then it will restart at 600 s.

If you run FDS through the PyroSim interface, then there are two options; you can Kill the job or Stop the job. If you choose the latter, then the .RESTART files are written as the job shuts down.

See section 7.3 of the FDS Users Guide.

The developers describe the restart feature as being fragile; it has become more reliable over the years, but the longer the simulation has run, the less likely you are to be able to successfully restart it.

Yes, from my experience, I want to say that you will lose data. So once an hour, copy and save data in txt.

Hi,

I was checking this post from the Thunderhead website: https://www.thunderheadeng.com/2019/12/__trashed-2/

They use the model of a T-Rex and it is huge. When I download the same file and imprt it to use it in a profile, I get a tiny version, does anyone know why that happens? I have tried with multiple fbx models and some (usually the ones that represent a person) are displayed with a normal size but others are very small.

Thanks!
