Modeling Jet Fans, Part 3 (now replaced by new post): Applications

April 12, 2015
In this post we use the FDS and the Dynamic Smagorinsky turbulent viscosity model to simulate both a full-scale jet fan experiment and clearing of smoke from a car park garage. Read More...

Modeling Jet Fans, Part 2 (now replaced by new post): An Engineering Approach

March 16, 2015
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...

PetraSim – How we extract a surface from a set of XYZ points

March 3, 2015
In the latest release of PetraSim we have improved the method we use to extract a fault surface from a set of XYZ points. The challenge is that we know the points are on the surface, but we do not know how the points are connected to define the surface.  Read More...

Radiative Fraction and Q_RADI Output

February 26, 2015
The heat released as a fire burns is distributed to the environment primarily through convection and radiation. But, when you check the FDS output files you may see a different fractional amount of radiation in the Q_RADI column. Read More...
