<div>Hi,</div>
<div><br>
</div>
<div>I have a serial vtu dataset provided by one of my users. Their current code can produce this in either ascii or inline binary. I am currently trying to convert this to appended binary (ultimately to pvtu with appended binary).</div>
<div>I'm having trouble, which I now believe may stem from the data containing VTK_POLYHEDRON. </div>
<div><br>
</div>
<div>I have a simple python script that I use with pvbatch to do this conversion, but I see the same results when I load the original data set with ParaView (4.1.0, in client/server mode), and use the Save Data option and save as vtu.</div>
<div>I get the same results for each input format (ascii or inline binary), and output format (ascii, binary, appended).</div>
<div><br>
</div>
<div>The first few lines of the original vtu file look like this:</div>
<div><br>
</div>
<div><?xml version="1.0"?></div>
<div> <VTKFile type="UnstructuredGrid" version="0.1" byte_order="BigEndian"></div>
<div> <UnstructuredGrid></div>
<div> <Piece NumberOfPoints="1699427" NumberOfCells="384126"></div>
<div><br>
</div>
<div>The first few lines of the converted file look like this:</div>
<div><br>
</div>
<div>offset="177748206"ructuredGrid" version="0.1" byte_order="LittleEndian"></div>
<div> <UnstructuredGrid></div>
<div> <Piece NumberOfPoints="1699427" NumberOfCells="384126" ></div>
<div><br>
</div>
<div><br>
</div>
<div>Something is clearly getting jumbled at the beginning of the converted file. If I manually edit the header of the file to read <VTKFile type="UnstructuredGrid", there are still problems with the file. In that case the info tab in ParaView reports the
correct number of points and cells, but no geometry is drawn. I have successfully converted other vtu files using this same method. The primary difference that I've been able to identify is that the files that are not converting happily contain VTK_POLYHEDRON
elements.</div>
<div><br>
</div>
<div>Has anyone else seen similar behavior?</div>
<div><br>
</div>
<div>Thanks,</div>
