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...

Smoke Visibility and Obscuration in PyroSim

June 19, 2017
Smoke visibility and obscuration are critical outputs of a fire simulation. This post reviews how visibility is calculated in FDS, compares the calculation to experimental data, and discusses how smoke is visualized in the new PyroSim Results Viewer and in Smokeview. The comparison of VTT experimental images with predicted smoke visualization using PyroSim/FDS shows remarkably good correlation.   Read More...

May 16, 2017
This screen cast covers a method that can be used to build a 3D model in SketchUp Make, and then export the geometry for use in PyroSim. Read More...

Ramps in PyroSim/FDS

May 16, 2017
This post shows how to draw a ramp in PyroSim, using triangular slabs to approximate the geometry. Ramps are useful when modeling parking garages or pedestrian walkways. Read More...

Heat Conduction in PyroSim/FDS

May 10, 2017
FDS assumes one-dimensional heat conduction into the surfaces of solid obstructions. With proper modeling, you can couple the front and back face temperatures of an obstruction so that heat flows through the obstruction. This post demonstrates heat transfer through obstructions, including radiative and convective fluxes on the surface.  Read More...

Using PyroSim/FDS to Maximize Solar Panel Convective Cooling

April 18, 2017
Solar panels are most efficient if they operate at lower temperatures. We are installing solar panels on a workshop roof and the question arose, "What is the best solar panel spacing to maximize solar panel convective cooling?" This post uses PyroSim and FDS to evaluate some different solar panel mounting options to maximize solar panel convective cooling.  Read More...

FEMTC 2016: Circulation, Ingress, and More

September 13, 2016
Circulation movement is often a critical part of the analysis for high occupancy areas with lots of foot traffic. As research and technology improves, engineers are adding non-evacuation investigations to their résumés. Jennifer Wiley, a Fire Protection Engineer at Jensen Hughes, will discuss these other uses for people movement models at the Fire and Evacuation Technical Modeling Conference (FEMTC).  Read More...
