[CIG-SHORT] Fwd: Question about saving both h5 and vtk file

[Li, Teng]

Hi Brad,

The reason I need both HDF5 and VTK files is because I would like to post process the data by using HDF5 file in Matlab. Post processing by using Matlab is more convenient and powerful. In order to make sure the results are right, I also need to use Paraview to show the data VTK file. That's why I think I need both kinds of output.

Best,
Teng

Teng,

In designing the PyLith output we assume a user will only want to output
information to a single format. For the solution fields it is possible
to output the same information in multiple formats by simply creating
additional output managers even though this was not the intent of the
design. However, for state variable output we only provide one output
manager, so you must pick one format. For real research applications, we
strongly recommend people use the HDF5 writers as they are much more
efficient as writing binary HDF5 files is much faster than writing ASCII
VTK files.

If you describe why you think you want both HDF5 and VTK output, we can
probably point you in the right direction for how to use HDF5 output in
the way you intend.

Regards,
Brad
