Fire_V8

The translator Fire_V8 creates the mesh in .flm format for Fire V8.

To create the input files, "Select solver" → Fire_V8 in the "Output" menu. After clicking "Write input " you can specify the following options for the interface:

option to create ASCII file
option to give a scaling factor for each direction (default is 1.0)
give the name of the output file

The program supports part names for faces and cells. Other boundary conditions are not supported.

Fire_V7

The translator Fire_V7 supports Fire files for the Fire Versions v7.0 and v7.0b_pl3. Supported Fire files are:

GEO-FILES (formatted, direct access): contains Cartesian grid coordinates
LNK-FILES (formatted, direct access): contains cell information and node properties.

To create the input files, "Select solver" → Fire_V7 in the "Output" menu. After clicking "Write input " you can specify the following options for the interface:

select the version of the fire files (7.0 or 7.0B PL3)
option to give a scaling factor for each direction (default is 1.0)
give the prefix name of the output file

The geo and lnk files are named prefix.geo and prefix.lnk.

Supported boundary conditions for FIRE V7

The program supports node properties, which are written in the .lnk file. Note that at common edges higher node properties have higher priority.

New in Fire Version 7.0b_pl12:

The program supports part names for faces and cells:

> 7.0 RECORDS=No I*12 UNITS=No BYTE/UNIT=12 FACELIMITNameStatus

> 7.0 RECORDS=7 I*12 UNITS=384 BYTE/UNIT=12 CELLLIMITNameStatus

Name can be any part name. Status determines wether the family is active (1) or not (0). The interface automatically sets every status to 0 (inactive). The user needs to activate them in Fire.
