<br>
Is there a way to specify the integer precision of polydata index arrays when using the Xdmf3 writer? For me, it's currently writing out indices in 64 bits, which is a bit wasteful given the number of vertices:<br>
<br>
<?xml version="1.0" encoding="utf-8"?><br>
<Xdmf xmlns:xi="<a href="http://www.w3.org/2001/XInclude" rel="noreferrer" target="_blank">http://www.w3.org/20<wbr>01/XInclude</a>" Version="3.3"><br>
<Domain><br>
<Grid Name="Grid"><br>
<Geometry Origin="" Type="XYZ"><br>
<DataItem DataType="Float" Dimensions="39010488 3" Format="HDF" Precision="4">region-rbc-9.h5:<wbr>Data2</DataItem><br>
</Geometry><br>
<Topology Dimensions="77777920" Type="Mixed"><br>
<DataItem DataType="Int" Dimensions="311111680" Format="HDF" Precision="8">region-rbc-9.h5:<wbr>Data3</DataItem><br>
</Topology><br>
</Grid><br>
</Domain><br>
</Xdmf><br>
<br>
Or is the output precision of (most) VTK writers fully determined by the compiled-in ID type?<br>
<br>
Thanks,<br>
Paul<br>
