Add metadata to hdf5 ouput #28
Description
It would be very useful if the hdf5 files were more descriptive.
A group with metadata such as
-type of file (hydrodynamic, lagrangian, waterproperties, external interpolated solution, ...)
-dimensionality of the encased solution (3D, 2D, 1D)
-type of mesh
-version of mohid or tool that produced it
-...
Every file should have this printed by mohid, by default, to help with the development of more semantically intense post processing tools.
