1.2. Version 3 most important changes
WEBSITE Change, From December 1st 2019 the official web site of flair is
with an alias the
Support to the www.fluka.org is discontinued.
Flair v3 is being completly restructured and based on python v3. Previous versions of flair (until v2.5) were based on Python v2. On January 1 2020, python v2 will no longer be supported by its creators
and all major Linux distributions are already moving away from it.
Flair v3 supports ONLY the FLUKA.CERN version.
The flair front-end interface is separated from the FLUKA functionality, which permits the developers the easy integration of other simulation codes which are input based (and not only).
The long term plan will be to fully support from the same interface CERN FLUKA, PENELOPE, Geant4, MCNP, PHITS, permitting the user to test/benchmark various simulations codes using the same input.
From v3 the master input file for flair is the “.flair” project file (no longer the “.inp”). i.e. the whole FLUKA input file is stored in the “.flair” file in an text human readable way.
Input Editor is now based on a Text widget and no longer on the Canvas. This gives more flexibility to operate as a text-editor, with considerable improvement in performance. (i.e. a huge input file of 25000+ cards was taking almost 20s in the past to be displayed in the input editor, now on the same computer it takes less than 3s.)
The geometry engine is restructured to allow its use as a geometry navigator for simulation programs, allowing the easy integration of the present FLUKA input geometries in Geant4.
There are numerous improvements in the geometry engine for a better user experience, i.e. more logical error checks, 3D plots are enhanced with ambient occlusion for photorealistic shadows, and faster adaptive antialiasing and edge detection.
