Hi, Foamers,

I forked beatlejuice's repo of IOH5Write on Github, and I have added some extra code for IOH5Write to support polyhedral meshes.

Now IOH5Write can process polyhedral cells, write the cells and datas to .h5 files, which can be read into recent versions of Paraview via the XDMF3 reader.

The repo url is https://github.com/oseen/IOH5Write/

The key commit is:

https://github.com/oseen/IOH5Write/c...999f0114bf2ee3

The code was tested on both OpenFOAM-8 and OpenFOAM-v2012, and because the APIs of OpenFOAM-8 and OpenFOAM-v2012 are slightly different, another branch named IOH5Write_b_OFv2006 was created for OpenFOAM-v2012.

you can find the latest code "IOH5Write_b_OF6" (works with openfoam6) in the github branch:

The previous code IOH5Write_b" (works with openfoam-2.3.1) can be found in the github branch:
https://github.com/ipat-fau/IOH5Write/tree/IOH5Write_b

I think Hakon's "IOHWrite" is a useful library and it is worth updating it and share it with the community so that it can also be improved by the community.

I hope it is useful and maybe helps somebody.

Cheers

Hey,
Thanks for your interesting work. I faced issues when using the library with more than 1024 cores. I use mpt instead of open-mpi however, I do not think this causes the issue. I have not yet went through the code to debug, but have you ever tested the library for such parallel simulations?

The error starting from, and go all over hdf5 library functions :
H5Dcreate2(): unable to create dataset

minor: Unable to initialize object
