Does Geant4 only support predefined materials. I have users of my FreeCAD GDML workbench stating they have to delete the whole materials section of the GDML file by hand.
If the user has used/selected any Geant4 material it will not appear in the materials section. The materials section only contains definitions that would not be the standard ones.
Just received an email stating
In geant4, there is a example which load gdml file
I have just tested it and It works well!
I am confused.
Geant4 (the code) certainly supports both predefined materials (through the
G4NistManager) as well as building your own materials by instantating
The GDML interface should support both (e.g., if you reference
G4_Cu material, it should pull that from
G4NistManager, or if you define your own copper with its own name in the <material> section, that should also work.
Thanks - Okay Programmer error, I found a bug in the output of Non predefined Geant4 material, hopefully now fixed.
