<p class="MsoNormal" style="margin-bottom:12.0pt">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). <o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">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.<o:p></o:p></p>
