Unable to use damask.Grid.load_DREAM3D method

[Zak-ship-it]

Hello,
I am using DAMASK (version 3.0.0a7.post0), and I need to create .vti/.yaml from DREAM3D files.
However, I have encountered an issue while attempting to load a .dream3d file using the damask.Grid.load_DREAM3D method.
The .dream3d file was generated with the DREAM3D software, and I have attached it to this message for your reference. When I attempt to execute the command damask.Grid.load_DREAM3D('Cylinder_Synthetic.dream3d') , I receive the following error message:
KeyError: "Unable to open object (object 'Phases' doesn't exist)"
Despite specifying phases='Phases (partial)' as indicated by the data I observed when opening the XDMF file.
I would greatly appreciate any assistance or guidance you could provide to resolve this issue. Thank you in advance.
Regards,
Ali

unfortunately, the flexibility of the DREAM.3D format makes it very hard to parse. In your case, there are two groups (folders) that contain the spacing information: DataContainers/Sampled_Cylinder and DataContainers/SyntheticVolumeDataContainer. The latter one contains all the relevant information, but the first one is used as the base group. Specifying the correct one solves the issue:

g = damask.GeomGrid.load_DREAM3D("Cylinder_Synthetic.dream3d",base_group='DataContainers/SyntheticVolumeDataContainer')
