[Paraview] [EXTERNAL] Re: pvtm file format

[Scott, W Alan]

Thanks Andy.  I’m hearing of numerous issues like thus, trying to wrap my head around same.

Let’s start with a few questions.  Where is the .pvtm file format documented?  Google doesn’t know...  Next, why have two redundant file formats?  One should be deprecated.  Why can Catalyst write this file format?  And last, of course, why can’t ParaView read it?

The .pvtm is the same as the .vtm file, just a redundant file extension. Really, the .vtm format is parallel/partition aware where as the other .vt* extensions have a partitioned .pvt* format.
I'm a bit surprised that PV doesn't associate the .pvtm file with multiblock datasets. If you try to read in a .pvtm file though you just need to properly associate it with the XML multiblock data reader.

I’ve never heard of these files either.  From my user:




I am writing planes of data in parallel with XMLMultiBlockWriter and it is generating *pvtm files.  However, paraview doesn’t seem to support this file format for reading?  I am trying to visualize the results and I can read the individual *vtp files, but it doesn’t accept the parallel file.

Then:


I will try to put something together for you soon.  I am writing this dataset from a slice while running catalyst.  I found a work around by using the MergeBlocks filter on the slice and then dumping that as an unstructured grid via XMLPUnstructuredGridWriter.

Back to me.

“.  I am writing this dataset from a slice while running catalyst.”  So, I figured I would start by asking if this is a Catalyst/ ParaView/ VTK file format (that I had never heard of)...    I have asked user for a dataset.

Thanks,

Alan

I am not sure. A quick grep through the code in ParaView/VTK doesn't yield a hit. What's the context in which you encountered this?

What is a .pvtm file?  How can I make one with sources?

Thanks,
