[Paraview-developers] H5Part and H5Hut

[Amit Goel]

Hi John

Thanks a lot for your kind response. There are two parts to my question:

1. Creating H5Part Files: Which version of H5Part should I use for creating “parallel-hdf5 based H5Part” files - H5Hut 1.99.13 or H5Part 1.6.6 ? Is this code on git somewhere ?

2. Reading H5Part Files in PV: As I understand from your email, I shall try pv-4.4 branch after I have created them.

Looking forward for your kind advice on point 1 mentioned above.

Regards

amit

the version of the reader that I maintain is kept here
https://github.com/biddisco/pv-meshless

It has a number of extensions and options that you will want to ignore.

You will see that the pv-4.4 branch was was tested against the paraview master branch a few months ago. if it doesn’t compile against or work with the latest master, please let me know as I only work on viz/paraview stuff part of my time, so I don’t get to maintain/update this as much as I’d like.

Note:
For parallel partitioning of particle data, you will want the pv-zoltan plugin

Dear Berk

Thanks a lot for your response.

I was able to open H5part files, albeit with warnings in H5Part. Further, there seems to be multiple versions of H5Part floating around:

H5Hut 1.99.13
H5Part 1.6.6

Although the user manuals on H5Part and H5hut website describe the same structure for H5Part files, but seems like codes did go through a major restructuring. I also looked at code of Paraview H5PartReader plugin but was not able to find which version of H5Part code was embedded in reader. Further the H5Part code files itself have been made part of reader, thus plugin doesnt rely on separately present H5Part libraries.

I dont mind digging in and updating the H5Part Plugin and submit patches, but only if I knew where to find the latest stable version of H5Part itself. :-)

Having said that, I am now trying Gadget HDF5 format as my ultimate goal is to save my particle simulations in some HDF5 format and then render through Paraview.

Are there any other particle formats based on HDF5 that Paraview supports ?

Regards

Amit

Hi Amit,

I CC'ed John who is the original author of that plugin. Hopefully, he can answer your question.
Maybe there is an updated version of the reader that handles a newer format. We would be
happy to update the plugin if there is a new version of the reader.

It does not look like H5hut is available so I can't speak to it. We are not currently doing any
work on the H5Part reader. As far as I know, we haven't received any user requests asking us
to update or fix it so far.

Best,

Hi

I am new to this list. Please let me know if anyone knows the status of H5Part plugin ? My specific questions are:

1. How to use it exactly. I tried opening a Cavity sample file from pvmeshless site. But it returns errors and warnings.

2. What is status of H5hut and H5Part plugins in forthcoming versions of Paraview ?

Regards
