PyroSim 2014.2.0807

August 7, 2014

This is a maintenance release of PyroSim. The release includes updates for FDS and Smokeview as well as a fix for a bug with the Front and Left camera modes in the 2D View. Read More...

PyroSim 2014.2.0731

July 31, 2014
This is a maintenance release of PyroSim. This release includes updates for FDS and Smokeview, an improvement to the cluster execution feature, and bug fixes. Read More...

Radiation and Convection on Surfaces

April 25, 2014
Every solid surface in an FDS model defines convective and radiative flux thermal boundary conditions. Each of the terms are always being calculated, sometimes using default parameters that may not have been explicitly set. Read More...

PyroSim 2014.1.0331

March 31, 2014
This is a maintenance release of PyroSim. This release includes bug fixes and changes to the way PyroSim handles species. Read More...

Modeling Fire, Part 4 Addendum – Re-Analysis using HRRPUA Curve

March 19, 2014
This is an addendum to the Part 4 video on fire modeling. We re-analyzed the problem, changing the Heat Release Rate Per Unit Area (HRRPUA) from a constant value to a function (or curve). Read More...

Modeling Fire, Part 4 – Combustion with HRR, Ignition, and Burn Away

March 5, 2014
In this video we show how to model a fire using a specified heat release rate per unit area (HRRPUA), an ignition temperature, and burn away. This is about as complicated as models can be made without also simulating pyrolysis. Read More...

Modeling Fire, Part 3 – Combustion using HRR

February 23, 2014
FDS can be a useful tool for both a fire protection engineer and a fire researcher. The challenge is that this can result in a bewildering array of options with respect to modeling the combustion process. Read More...

Modeling Fire, Part 2 – Heat Release Rate

February 14, 2014
When we specify a Heat Release Rate, we are really specifying the rate at which fuel is released into the fire simulation. The fuel mass flow rate is calculated so that combustion will release heat at the desired rate. Read More...

Modeling Fire, Part 1 – Reactions

February 14, 2014
All PyroSim (FDS) models that include combustion must define a gas phase reaction that converts fuel to combustion products. We review the "simple chemistry" approach in FDS. Read More...

Using PyroSim for Parallel Processing of Multiple Meshes

January 27, 2014
This video shows reasons to use multiple meshes, rules and guidelines for defining multiple meshes, how to use the multiple mesh tools, and how to run a parallel processor solution. Read More...
