Managing Quality in Fire Safety Design Projects Involving RSET Analyses

December 13, 2017
Many modelling approaches can be used to assess evacuation time of buildings in fire situations. We present in this paper a new model, implemented in a collaborative work between LEMTA and CNPP, and based on a macroscopic continuous approach. Read More...

An Emergency Egress Model Based On A Macroscopic Continuous Approach

November 28, 2017
Many modelling approaches can be used to assess evacuation time of buildings in fire situations. We present in this paper a new model, implemented in a collaborative work between LEMTA and CNPP, and based on a macroscopic continuous approach. Read More...

Fire Scenarios Assessment

November 28, 2017
In 2008, the DIN working committee NA 005-52-21 AA started its work to standardize fire safety engineering methods in Germany. The second subdocument DIN 18009 Part 3 shall cover the design fire scenarios and design fires. Some ideas related to methodology, requirements and scenario-based design are presented in this article. Read More...

November 15, 2017
This update includes additional support for FDS features including leakage, linear device arrays, and advanced HVAC records; reliability improvements for local parallel FDS simulations; and a new default results viewer. Read More...

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...

August 28, 2017
This release fixes problems with the HydrateResSim user interface, improves Petrel import support, and fixes crashes related to viewing results.  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...
