Modeling Jet Fans, Part 3: Car Park Simulation

April 11, 2016
In this post, we explore modeling jet fans to extract smoke from a car park using FDS. The jet fans are modeled using HVAC ducts with shrouds. 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...

FDS Cluster Free Upgrade for PyroSim

March 28, 2016
PyroSim 2016.1 is set to release in the next two weeks, including support for additional DEVC fields and new CAD file import options similar to those added in Pathfinder 2016.1. In addition, all PyroSim licenses will now include unrestricted use of the cluster simulation option. This is a permanent change which will automatically take effect, saving users 30% of the cost of purchasing PyroSim with the Unlimited Cluster Option. Read More...

Velocity Patch in FDS

Measurement Regions for Density & Velocity

March 10, 2016
Pathfinder 2016 includes a new UI object called measurement regions. These red boxes record density and velocity values to a CSV file. They are drawn over the navigation surfaces in areas of steady flow. Read More...

Hydrostatic Pressure Conditions in PetraSim/TOUGH

March 9, 2016
This is the first in a series of posts discussing the initialization of a TOUGH model to represent realistic natural state conditions.  In almost all cases, it is beneficial to run a model to steady state before adding transient boundary conditions, injection or pumping wells, etc.  We’ll give a very simple example first, where we’ve used EOS3 to establish a hydrostatic pressure gradient in a single phase model. Read More...
