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...

In Brian's second talk at FEMTC 2020, he presents an overview of research and development at Thunderhead Engineering in the years since FEMTC 2018. If you haven't yet watched his first presentation, you can view it now for a deep dive into Pathfinder movement behavior research. This presentation covers the bulk of many other topics we've focused on. Read More...

Want to learn how to improve your fire modeling skills? Dave McGill has worked with Thunderhead Engineering to provide PyroSim and FDS training to hundreds of attendees for many years. We are excited to announce the latest dates, viewable at our online schedule, for his acclaimed courses in an online workshop format. Read More...

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...
