Critical Velocity in Tunnel Fires

May 17, 2016
Merve Altay contacted us with a tunnel model that was experiencing a numerical instability. He was simulating a set of experiments performed to evaluate the critical velocity in a tunnel fire. Answering his question eventually led to improvements in FDS and a better understanding of user applications of PyroSim/FDS.  Read More...

Modeling Jet Fans, Part 2: Validation using Experimental Data

April 11, 2016
It is not feasible to simulate full scale parking garages with such a fine mesh, even if multiple meshes are used. This post discusses ways it may be possible to use a larger mesh size and still obtain meaningful results. Read More...
