Importing FDS Validation Examples into PyroSim

October 23, 2017
The FDS validation suite compares FDS (Fire Dynamic Simulator) results with experimental data. These examples cover most of the features of available in FDS. When you want to use a new feature in FDS, you can speed your learning by reviewing how the feature was used in a validation example. This post shows how you can quickly import the FDS model into PyroSim.  Read More...

Fire Modelling Of Energy-Efficient Apartment Buildings

August 7, 2017
In this work, we wanted to study how the construction trends aiming at energy efficient and high-rise buildings are changing the fire modelling practices. Through experiments, FDS validation and a simulation case-study, we investigate the reliability and modelling practices of the mechanical ventilation systems and air-tight building envelopes. Read More...

Pathfinder at People Movement and Management Show

July 31, 2017
In July of 2017, Thunderhead participated in the People Movement and Management Show held in Derby, UK. Our goal was to introduce Pathfinder to the people movement audience. Pathfinder was originally developed for emergency evacuation simulation as a companion product to PyroSim, our fire simulator. But we are adding features that will make it possible ... Read More...

Exploring Unstructured Poisson Solvers for FDS

July 11, 2017
The paper and its associated talk are intended to give some insights into the current state of development and to compare the pros and cons of the different Poisson approaches with respect to their ef´Čüciency and accuracy. Read More...

Implementing Assisted Evacuation and Integrated Fire Model Results in Pathfinder and PyroSim

June 20, 2017
This presentation provides an update of recent developments in PyroSim and Pathfinder, including improvements in model and results rendering, integrated fire results visualization, and new behaviors for assisted evacuation modeling. Read More...

Tenability Criteria In Unique Situations And Atypical Buildings

June 20, 2017
This presentation will look at tenability in atypical buildings such as prisons and enclosed amusement rides. This includes how increased exposure times, due to code changes and unique building applications, effect applicable tenability criteria. The basis for the presentation includes case studies and criteria that has been used in prisons throughout the United States of America and amusement parks throughout the world. Read More...

A Research Roadmap For Evacuation Models Used In Fire Safety Engineering

June 20, 2017
This paper wants to open a discussion on a research roadmap for evacuation models used in fire safety engineering. In other words, this paper explores what features need to be possibly implemented, improved, or expanded in existing evacuation models for fire safety engineering applications. Read More...
