Actually I installed a solar-powered whirlybird a few weeks ago in my shop and it worked great! Try it. It's much better to protect your roof by heat and humidity with a whirlybird that can guarantee a good amount of longevity to your rood and consequently to your house. I had some great issues to overcome when I renovated my father's home and one of the best advices I got from a good pal of mine who works in construction is to add a solar whirlybird in the mix. I still enjoy a much cooler house in the summer times here in Cairns thanks to it.

That's a good question to ask. I think a good idea is to install an exhaust fan if you have a roof.

Hello!

I am using both Pyrosim and Pathfinder. I can calculate the FED for selected occupants by importing Plot3D results data from Pyrosim simulation. Also, there is a way for manually coupling FDS results with Pathfinder to modify walking speed according to visibility. Does Pathfinder have any automated way for this integration now?
From which Pathfinder version is it possible to calculate the FED for occupants using FDS data? I need this for reference in my writing.

A reply is highly appreciated.

Thank you.

I want to simulate a wheelchair to evacuate through the elevator, but the wheelchair cannot enter the elevator!

Good day to everyone,

Just checking on the following. I am conducting a recirculation study (i.e. to show that the smoke exhausted from a vent does not recirculate back into the Fresh Air vents for the same system at the external). Therefore instead of modelling an actual fire (e.g. 5MW) in the compartment and modelling the smoke movement through the ducting system all the way to the external, i have instead modelled a burner surface at the external with these parameters:
a. Supply (to modelled exhausting of smoke)
b. Thermal boundary conditions - using the Boundary Condition Model for Fixed Temperature (utilizing the hot smoke layer temperature based on prescriptive calculations)
c. Species Injection - Soot Mass fraction of 0.1kg/kg

I would like to enquire if the setting of the soot mass fraction as such is equivalent to the setting of soot yield as 0.1 in the byproducts?

Aside to the above, in terms of tenability criteria, can it be said that a visibility more than 30m is considered to be equivalent to no smoke recirculation? if yes can i know if there are any codes i can use to substantiate this. If no, what would be an acceptable method or criteria to use when defining recirculation (or lack of smoke circulation)

Thank you and Regards
Karthik

In addition, the video file of the results is out of place.

The mouse cursor is a jump, does not select an object from the correct location, and 3D navigation is a jump.
At the same time in previous work, the program works correctly.
What could be the problem?
Thank you.

Is there a way in pyrosim to add overlay=false to an obstruction?

I would like to ensure that a gypsum wall surface has priority over an inert room infill.

I am trying to simulate an ammonia leakage in a engine room of a ship using Pyrosim. I am getting this error on running FDS. Can anyone please help me in correcting what I am doing wrong?
