I’m using vtkMultBlockDatasets and I want to attach metadata to some of the Blocks, persist that metadata to disk and then use it when I read the file later.
So far, I’ve been successful using the provided NAME metadata associate a name with the Block
But now I need to add more data and I’m not having any success.
I tried two approach so far,
First, using field data
assembly = vtk.vtkMultiBlockDataSet() block_type = vtk.vtkStringArray() block_type.SetNumberOfValues(1) block_type.SetName("blocktype") block_type.SetValue(0, "Assembly") assembly.GetFieldData().AddArray(block_type) field_data = assembly.GetFieldData().GetAbstractArray("blocktype") print(field_data.GetValue(0))
The field data is added and recovered but is NOT exported when I write the file to disk using vtkXMLMultiBlockDataWriter()
Then I tried using one of the other standard keys,
But this is not present in the exported file either.
How can I attach metadata to Blocks and have this data exported to disk?
Thanks in advance,
