FDS TutorialIn this tutorial you will learn how to model a Radially Spreading Fire, both on a flat plane and among obstructions. All of this will be accomplished without modeling the pyrolysis of the solid fuels directly. 1. Why model a radially spreading fire? This function is commonly used to emulate a realistic fire growth/spread. It […]
In this tutorial you will learn how to remove obstructions during a simulation in FDS. 1. Introduction Devices can be used to control various actions. One of the most frequent controls implemented in a FDS simulation is the removal (or creation) of an obstruction. In this tutorial we will remove obstructions using basic control actions. […]
The goal of the FDS simulation presented in this page is to evaluate the oxygen volume fraction over time in a Staircase fire. 1. Simulation summary The specific simulation inputs that determine the oxygen volume fraction are the following: The following video shows the results of the simulation; Here is the video: 1.2. Input parameters […]
In this Fire Dynamics Simulator tutorial, you are going to learn how to properly define multiple meshes in the same FDS simulation. Mesh Basics All FDS calculations are performed within a domain that is made up of parallelepipedal volumes called meshes. Each mesh is divided into rectangular cells, the number of which depends on the […]
