VTKHDF file format

[flabowski]

Is it possible to save a vtk_file in the VTKHDF file format? The vtk docs say, that

This is a file format using the same concepts as the XML formats described above but relying on HDF5 for actual storage.

Sorry if this is obvious, I am new to this library and vtk file formats.

@flabowski Hi,

I have not read the HDF support inside the VTK file format. Anyhow, VTKFortran currently does not support VTKHDF. Currently, I am very busy, and introducing the support to VTKHDF is a low priority for me. Indeed, I use a lot HDF5, but I use directly the fortran binding provided by the HDF group which is very well done.

I leave this help request open in case anyone would like to help me to implement VTKHDF support.

Kind regards,
Stefano

@flabowski I am starting to think about this feature (with Claude's help). You can track the evolution in #51

Thats great to hear, I'd be happy to test it.
Also, I recently implemented VTK XML internal compression for '.vtu' files (format='raw-zlib', its behind an optional VTKFORTRAN_USE_ZLIB). It cuts file size and ParaView can read it directly. I can open a PR so you can see if its intesting for the project.
