Fire Simulation for Engineers/FDS/General Configuration

First, general configuration is performed.

The case receives a name via the  namelist group, the simulation time is set via the   namelist group. Other miscellaneous parameters are prescribed via the  namelist group.

Naming the job,
The first thing to do when setting up an input file is to give the job a name. The name of the job is important because often a project involves numerous simulations in which case the names of the individual simulations can help organize the effort. The namelist group  contains two parameters, as in this example:    is a string of 30 characters or less used to name the output files created by FDS. No periods or spaces are allowed. is a string of 60 characters or less that describes the simulation. It is simply a descriptive text that is passed to various output files.

It is always convenient to exactly use the same string for the name of the input file and the. For example, if you name  the input file, then set   in the   namelist group.

Only one  line can be entered in the input file. The following table summarizes some of the most used  parameters.

Simulation time,
is the namelist group that define the time duration of the simulation. Usually, only the duration of the simulation is required on this line, via the parameter. The default is 1 s.

For example, the following line will instruct FDS to run the simulation for 5400 s: If  is set to zero, only the set-up work is performed, allowing you to quickly check the geometry in Smokeview.

Only one  line can be entered in the input file. The following table summarizes some of the most used  parameters.

Miscellaneous,
is the namelist group of global miscellaneous input parameters. Many parameters for  exist, some of them are explained later in this manual.

For example: establishes that all bounding surfaces are to be made of steel unless otherwise specified.

Only one  line can be entered in the input file. The following table summarizes some of the most used  parameters.
