<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello Catalyst developers<br>
<br>
I have my first parallel simulation interfaced with Catalyst live. I use PV 5.1.2<br>
<div><br>
While the live display has all the pieces, with the correct sub-extents, and the renderview shows the full grid without any missing piece, I find that the Parallel Image Data Writer does not correctly write the WholeExtent, using the 0-th piece's extents, instead
of the global extent. Correcting the output by hand, enables me to later view the full grid. So, all pieces are correct, I only have a problem with the WholExtent. For example, running on 4 MPI tasks, I get<br>
<br>
<VTKFile type="PImageData" version="1.0" byte_order="LittleEndian" header_type="UInt64"><br>
<PImageData WholeExtent="0 11 0 11 0 0" GhostLevel="0" Origin="0 0 0" Spacing="1 1 1"><br>
<PPointData><br>
<PDataArray type="Float64" Name="temperature"/><br>
</PPointData><br>
<Piece Extent="0 11 0 11 0 0" Source="filename_624_0.vti"/><br>
<Piece Extent="0 11 10 21 0 0" Source="filename_624_1.vti"/><br>
<Piece Extent="10 21 0 11 0 0" Source="filename_624_2.vti"/><br>
<Piece Extent="10 21 10 21 0 0" Source="filename_624_3.vti"/><br>
</PImageData><br>
</VTKFile><br>
<div class="BodyFragment"><font size="2"><span style="font-size:10pt;">
<div class="PlainText"><br>
<br>
whereas the correct line should be<br>
<PImageData WholeExtent="0 21 0 21 0 0" GhostLevel="0" Origin="0 0 0" Spacing="1 1 1"><br>
<br>
is this a know issue?<br>
<br>
likewise, eventhough the live paraview renderview shows the full image, when I run my simulation and save screnshots, I only the image output of Task 0.<br>
<br>
Is this known? or is it a problem with my own code? I am puzzled by the fact that when connecting live to the simulation, all pieces are at the right places, so I do see a full resolution mesh. Why should the PNG and *pvti files be missing pieces?<br>
<br>
Thanks for any tips.<br>
