Monte Carlo Improvements in Pathfinder 2020.5

November 13, 2020

Since Pathfinder 2018.3, users have been able to take advantage of Monte Carlo simulations through a command line interface. In modeling, the Monte Carlo method is used to randomize inputs across many simulation instances. With a statistical analysis applied, users can create probablistic interpretations of the resulting data sets. It is often used in research and is also required by regulations such as RiMEA. Read More...

2020 R&D Overview – Past, Present, & Future

Visual Improvements in Results 2020.5

November 2, 2020
Since introducing our Results application which combines PyroSim and Pathfinder output into a single workspace, we have continued to improve the visual realism of this package. Our users report that improvements in rendering smoke, textures, and occupant animation not only give their work a more professional look, but also increase the clarity of their findings. In the 2020.5 release, we will add several new features to deliver even better modeling output. Read More...

Social Distance, Queues, and More Research

October 27, 2020
In September, Thunderhead Engineering welcomed a record attendance to FEMTC 2020 in its first virtual edition. We are excited to begin delivering the presentations from that conference to everyone. First, we have a discussion of several different occupant movement topics researched by the Thunderhead Engineering R&D team and presented by President Brian Hardeman. There's more to come! Read More...

Mars Colony Biome Evacuation Analysis by Szymon Matkowski

August 11, 2020
Our support team has been assisting Szymon Matkowski with his recent project based on a feasibility study, completed by a team at Wroclaw University of Science and Technology, of possible layouts and technical solutions for a theoretical base on Mars. The study was part of a competition sponsored by The Mars Society in which the ... Read More...

Social Distance Improvements in Pathfinder 2020.3

August 7, 2020
Pathfinder 2020.3 further enhances the user's ability to model social distance behavior as a method to address pandemic safety. Social Distance has been completely separated from Comfort Distance. Now, rather than Enable Forced Separation in the Simulation Parameters (retained in 2020.3 for legacy files), Social Distancing has its own selection field in the Advanced tab of the Edit Profiles dialog. With this recent development, occupants exhibit less "jostle" or "jitter" while smoothly and effectively maintaining distance. Read More...
