Hi all,
I have successfully used the JOIN Function for the XDMF reader to
concatenate the data from several HDF5 files.
<Xdmf Version="3.0">
<Domain>
<Grid GridType="Uniform">
<Topology Name="Fields topology"
TopologyType="2DCoRectMesh" Dimensions="21 10"/>
<Geometry Name="Fields geometry" GeometryType="ORIGIN_DXDY">
<DataItem Format="XML" NumberType="float"
Dimensions="2">0.0 0.0</DataItem>
<DataItem Format="XML" NumberType="float"
Dimensions="2">0.3 0.06</DataItem>
</Geometry>
<Attribute Name="By" Center="Node" AttributeType="Scalar">
<DataItem ItemType="Function"
Function="JOIN($0,$1,$2,$3,$4,$5,$6,$7,$8,$9)" Dimensions="21 10">
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000002/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000007/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000012/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000017/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000022/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000027/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000032/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000037/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000042/By</DataItem>
<DataItem ItemType="Uniform" NumberType="Float"
Precision="8" Dimensions="21"
Format="HDF">mystuff.h5:/0000000047/By</DataItem>
</DataItem>
</Attribute>
</Grid>
</Domain>
</Xdmf>
However, this technique only works when joining a maximum of 10
different pieces of data. If I add one DataItem in the JOIN Function,
ParaView crashes upon clicking "Apply".
Is there a reason for this? Am I doing something wrong? Is there a workaround?
Cheers
Fred
