GDML importing to FLAIR

Geometry and Materials

Hi, I am trying import GDML to FLAIR, but I got the same error massage "Traceback (most recent call last):

  File "/usr/local/flair/tkFlair.py", line 1357, in __call__
    return self.func(*args)
  File "/usr/local/flair/flair.py", line 1521, in importGdml
    gdml = Gdml(filename)
  File "/usr/local/flair/moira/gdml.py", line 57, in __init__
    self.read(filename)
  File "/usr/local/flair/moira/gdml.py", line 131, in read
    self._parseStructure(node)
  File "/usr/local/flair/moira/gdml.py", line 591, in _parseStructure
    self._parseVolume(child)
  File "/usr/local/flair/moira/gdml.py", line 614, in _parseVolume
    volume["physvol"].append(self._parsePhysvol(child))
  File "/usr/local/flair/moira/gdml.py", line 652, in _parsePhysvol
    self.read(str(child.attributes["name"].value), False)
  File "/usr/local/flair/moira/gdml.py", line 116, in read
    f = open(self.filename,"r")
FileNotFoundError: [Errno 2] No such file or directory: 'Volumes/Component11.gdml'

I got the same result for any GDML, what I exported from STEP files. i use the GUI Mesh.
The output folder has a mother.gdml file and a Volumes dir, containts multiple gdml files.

Update: I managed make a single file imported, and it is tessalated, and I am aware, that is not supported at the moment.

FLUKA does not have tesselated geometry capabilities builtin for the moment. So the importing from GDML will not work. It can only work for GDML geometries that are described up to 2nd degree solids.

If you want to use CAD geometries I would recommend to use the FLUDAG interface

Thank you for the answer Vasilis! I gonna give a run for the FLUDAG.
