<div dir="ltr"><div><div><div><div>Hi Jim,<br><br></div>Yes, currently Overlapping AMR data sets are not supported by Catalyst Live. This is because VTK doesn't support sending that data object. That would have to be changed in vtkCommunicator::Send(vtkDataObject* data, int remoteHandle, int tag). <br><br></div>A workaround would be to use a Threshold filter to convert to a multiblock of unstructured grids, use the merge blocks filter and then extract this output to the client. You'll get some warnings about the data set not being a polydata (think about running a large simulation and trying to transfer all of that to a separate server or client). I'm assuming since you're trying to fetch the entire data set that the use case isn't for an overly large data set.<br><br></div>Cheers,<br></div>Andy<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Mar 31, 2016 at 9:44 AM, <span dir="ltr"><<a href="mailto:Jim.Eliot@awe.co.uk" target="_blank">Jim.Eliot@awe.co.uk</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">I have been trying to use Catalyst Live with the CxxOverlappingAMRExample from the ParaView Catalyst Example Code repository [1] but I see an error when I try to visualise the data from a ParaView client. The client connects to the simulation
successfully and PVTrivialProducer1 appears in the Pipeline Browser. The Information tab shows it as an Overlapping AMR Dataset with 3 levels. However, when I click on the PVTrivialProducer1 icon, ParaView prints an error then segfaults. The error is something
like:<u></u><u></u></p>

<p class="MsoNormal"> Warning: In <src-dir>/VTK/Parallel/Core/vtkCommunicator.cxx, line 394<u></u><u></u></p>
<p class="MsoNormal"> vtkSocketCommunicator (…): Cannot receive vtkOverlappingAMR<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I have tried this with both ParaView 4.4.0 and 5.0.0 with the same results. The example works fine when I am using non-Live Catalyst (i.e. it writes out a bunch of vtm files that I can read into ParaView).<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">So I am wondering, are AMR meshes not supported by Catalyst Live? Do I have to handle AMR meshes differently when using Catalyst interactively?<u></u><u></u></p>
