<p>The thing that jumps out at me is missing the Dimensions tag on the function itself. For instance, we create our grids as:</p>
<p><br>
</p>
<p></p>
<div> <DataItem Dimensions="8 47 373 3" Function="JOIN($0, $1, $2)" ItemType="Function"><br>
<DataItem Dimensions="8 47 373" Format="HDF" NumberType="Float" Precision="8">grid.h5:/Domain_00001/x</DataItem><br>
<DataItem Dimensions="8 47 373" Format="HDF" NumberType="Float" Precision="8">grid.h5:/Domain_00001/y</DataItem><br>
<DataItem Dimensions="8 47 373" Format="HDF" NumberType="Float" Precision="8">grid.h5:/Domain_00001/z</DataItem><br>
</DataItem></div>
<p></p>
<p><br>
</p>
<p>We also use a comma between the JOIN, not a semicolon -- not sure if that matters or not.<br>
</p>
<br>
<p>If you change your JOIN to look like:</p>
<p><br>

<p>does that fix the problem?</p>

<span lang="EN-US">I am now working on a project which needs the use of JOIN function in xdmf to concatenate the data from multiple h5 files and visualize those files in Paraview. I have created a small trial to test this JOIN function. I create two h5 files,
each of which contains two points of a unit square. For each point, I assign a value to it as its attribute. Then I write one xdmf file, which uses function JOIN to concatenate the dataset from two h5 files. But when I load my xdmf file into Paraview, Paraview
just crashes directly. This is the xdmf file I have written:</span></p>

<span lang="EN-US">To avoid the problem of h5 file itself, I have also written two separate xdmf files for each h5 file and load each xdmf file separately into Paraview. I can successfully load these two h5 files separately into Paraview, so the problem might
no be my h5 files. Can anyone help me with this problem? Are there any mistakes of my ways of using JOIN function in xdmf?
