Hi Jim,
Yes, you can have a Catalyst instrumented code connect to something running
pvserver and have the pvserver connect to the client. At the end of the
Python generated scripts there should be a line that looks like:
coprocessor.DoLiveVisualization(datadescription, "localhost", 22222)
Here you just have to edit it to point to something other than localhost.
As for overlapping structured grids, there's no convenient
composite/multiblock data set for that like there is for Cartesian grids.
What you would need to do is use vtkStructuredGrids with blanking done
manually and then just add them in as blocks in a vtkMultiBlockDataSet. It
won't have the structure that the AMR specific composite data sets have so
it may be a bit slower for some filters but it should work pretty much like
you want for most stuff. Please let us know if you try this out and get
unexpected/undesired behaviour.
Best,
Andy
