Geometry importation: FBD proper format
FBD format
The FBD format allows the importation of geometry by means of the internal tools proper to Flux.
The file in FBD format is created and used only by PREFLU module of Flux and contains the geometry of the problem, respectively points, lines, regions, subdivision of lines for the automatic mesh.
Conversion
The entities of initial file in FBD format are read and converted into Flux entities as in table below.
| Entities of initial file | are converted into … |
|---|---|
| points | points defined by parameterized coordinates |
| lines |
lines of type
|
| faces | automatic faces |
| geometric parameters | geometric parameters |
| regions | regions |
Options for conversion
The options for conversion proposed to the user are of two types: general options for conversion available for all formats (Length unit and precision are automatically selected by Flux: meter and automatic precision
- particular options, specific to the format FBD
Structure of a FBD file
For more details about the FBD format refer to the Flux 2D documentation.
Specific options
The options for data conversion specific to the FBD format are presented in the table below.
| Option | Choice | Description |
|---|---|---|
| Convert the mesh lines | no (by default) | the mesh lines are not imported |
| yes | the user chooses to import the mesh lines |
