When an object is first created, and a type is selected, one of the following .dat files will be used as the default geometry:
|Object Type||Cartesian Grid||Polar Grid|
|Blockage (solid)||Box (grey 33)||Poldef (grey 33)|
|Blockage (solid+heat)||Box (red 15)||Poldef (red 15)|
|Blockage (fluid)||Box (transparent grey 33)||Poldef (transparent grey 33)|
|Blockage (fluid+heat)||Box (transparent red 15)||Poldef (transparent red 15)|
|Inlet / Angled-in||Box (transparent purple 194)||Poldef (transparent purple 194)|
|Outlet / Angled-out||Box (transparent light blue 214)||Poldef (transparent light blue 214)|
|Plate||Box (light brown 80)||Poldef (light brown 80)|
|Plate + heat||Box (orange 177)||Poldef (orange 177)|
|Thin plate||Box (light brown 80)||Poldef (light brown 80)|
|Foliage||Box (transparent light green 120)||Poldef (transparent light green 120)|
|Fan||Box (transparent white 154) or Cylpipe if circular||Poldef (transparent white 154)|
|Point_history||Box (transparent khaki 56)||Poldef (transparent khaki 56)|
|Fine grid volume||Fine (special wire-frame)||Polfgv|
|User defined||Box (khaki 56)||Poldef (khaki 56)|
|Null||Wirexyz (wire-frame)||Wirexyz (wire-frame)|
|Pressure relief||Box (transparent grey 21)||Poldef (transparent grey 21)|
|ROTOR||n/a||Poldef (transparent white 17)|
|Sun||Sun (transparent orange 177)||n/a|
|Transfer||Box (transparent green 183)||Poldef (transparent green 183)|
|Wind_profile / Wind||Wind (transparent mauve)||n/a|
|Celltype||Box (khaki 56)||Poldef (khaki 56)|
|Drag_lift||Drag (special wire-frame)||Poldrag (special wire-frame)|
|PCB||Box (green 121)||Poldef (green 121)|
These files are in the \phoenics \d_satell\d_object\public\default folder.
When the type of an object is subsequently changed, the colour and / or geometry file will be changed according to the above table, as long as the colour is set to 'Default based on object type.
If the colour is set to 'Colours in geometry file', the these colours will be used.
If the colour is set to 'Palette index' then the colour will not be changed.
A description of the data file format is given in How do I make my own Clipart/Geometry files for PHOENICS-VR?
On exit from VR-Editor, a file called FACETDAT is created, which contains the definitions of the all the facets for all the non-cuboid objects. This file is read and interpreted by EARTH.
It is possible to make VR-Editor use a different geometry from that displayed on screen to create the FACETDAT file. This can be useful if the displayed geometry contains more detail than is required for the simulation.
Geometries whose file names appear in the file \phoenics \d_satell \d_object \replace.lst will be replaced by the default cube, or any other geometry specified there. The default replace.lst contains:
* File name replace.lst --------------------------------------- 24.12.02 * * Geometries whose file names match those listed below will be * replaced by the default cube at the time of setting facet cells and * before writing facetdat file. If a second geometry name is listed, * that will be used instead of the default cube. * If a rotation code is required for the replacement geometry, it can * be specified after the second name. * fan fan1 fan2 fire fire2 window window1 window2 window3 window4 paddle elgouna1 elg8 elcomp1 elcorep frnt_whl cylinder 5 back_whl cylinder 5
On the last four lines, the second string contains the name of the geometry used to create the FACETDAT entry. On the last two lines, a rotation code is also specified.
