[Paraview] Multiple Pieces in one file

[Berk Geveci]

Is this a multiblock dataset? ParaView 2.4 and VTK 5 support multiblock
datasets. You have to create a .vtm file. The vtm file supports multi-block
as well as hierarchical structured AMR datasets. For more information, look
at the header files of these:

vtkMultiGroupDataSet
vtkMultiBlockDataSet
vtkHierarchicalDataSet
vtkHierarchicalBoxDataSet
vtkXMLMultiGroupDataSetReader
vtkXMLMultiBlockDataSetReader

The format is simple. The vtm file is a meta-file that points to other XML
files. Here is a small example:

<?xml version="1.0"?>
<VTKFile type="vtkMultiBlockDataSet" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
<vtkMultiBlockDataSet>
<DataSet group="0" dataset="0" file="test/test_0.vts"/>
<DataSet group="1" dataset="0" file="test/test_1.vts"/>
<DataSet group="2" dataset="0" file="test/test_2.vts"/>
</vtkMultiBlockDataSet>
</VTKFile>

You can also have distributed multi-block datasets. Each group corresponds
to one block and can contain one or more datasets. These "sub blocks" are
the distributed data.
