XML Writer create multiblock root associated FieldData TimeValue with temporal dataset
Opening a temporal multiblock dataset then saving the data as a .vtm file create a multiblock root associated FieldData with strange effect in ParaView. Using root associeated field data can have unintended effects in ParaView:
Steps to reproduce:
- Open ParaView
- Open can.ex2, Apply
- Save data as a .vtm file
- Inspect .vtm file
The resulting field data is visible in the .vtm file
<VTKFile type="vtkMultiBlockDataSet" version="1.0" byte_order="LittleEndian" header_type="UInt64">
<vtkMultiBlockDataSet>
<Block index="0" name="Element Blocks">
<DataSet index="0" name="Unnamed block ID: 1 Type: HEX" file="testCan/testCan_0_0.vtu"/>
<DataSet index="1" name="Unnamed block ID: 2 Type: HEX" file="testCan/testCan_1_0.vtu"/>
</Block>
<Block index="4" name="Side Sets">
<DataSet index="0" name="Unnamed set ID: 4"/>
</Block>
<Block index="7" name="Node Sets">
<DataSet index="0" name="Unnamed set ID: 1"/>
<DataSet index="1" name="Unnamed set ID: 100"/>
</Block>
</vtkMultiBlockDataSet>
<FieldData>
<DataArray type="Float64" Name="TimeValue" NumberOfTuples="1" format="binary" RangeMin="0" RangeMax="0">
CAAAAAAAAAAAAAAAAAAAAA==
</DataArray>
</FieldData>
</VTKFile>Another approach would be to write the field data on each leaf node instead.
