Attributes of FDS meshes

1.   On the Lists menu, click > Measurements > FDS Meshes.

The FDS Meshes list opens.

Note: In lists, you can use the  Attribute selection icon to show and hide attribute values (Selecting attributes and subattributes for columns of a list).

The list contains the following attributes:

Short name Long name Description

FireIncident

Fire Incident

Name of the fire event

FDSFileName

FDS filename

Name of the *.fds file that the file incident data is stored in. If a file name has been entered and you click on it, the path to the directory where the file is stored will be displayed.

FDS_XBOrigin

FDS_XBOrigin

Original position x, y, z for the cells in the FDS mesh, relative to the position of the fire event [m] in the Vissim network

FDS_XBOpposite

FDS_XBOpposite

Position of the corner point of the cell opposite the original position in the FDS mesh, relative to the fire event’s coordinate [m] in the Vissim network

Other columns contain specific FDS data. The names of the columns correspond to FDS conventions. The short name and the long name are identical. When you open the *.inpx network file, the relevant data is read from the *.fds file specified in the FDS Filename attribute.

Name Description

FDS_ID

Optional identification number for the FDS mesh from the *.fds file

FDS_I

Number of cells in x-direction

FDS_J

Number of cells in y-direction

FDS_K

Number of cells in z-direction

Showing and editing dependent objects as relation

The attribute and attribute values of this network object type are shown in the list on the left, which consists of two coupled lists.

1.  In the list on the left, click the desired entry.

The list on the right contains attributes and attribute values of network objects, and/or base data allocated to the network object selected in the list on the left (Using coupled lists):

  • Plot 3D Files Timestep for each FDS mesh:
  • FDS simulation time: Period of time required for the FDS simulation from the *.fds file
  • Simulation time: Period of time calculated on the basis of FDS simulation time + time offset
  • File name: Name of the Plot3D file *.q. The file contains data on the quantities specified in the corresponding *.fds file.
