The hdf5 output is often easier to deal with in other programs.
Some time ago there was discussion and generally positive support for creating a set of example postprocessing scripts. I have some scripts that I could share with you or open a PR with but they’re for a couple of specific use cases
- reading 2D model results in MATLAB from hdf5 files
- reading 3D spherical geometry model results with python, averaging onto a regular or equispaced mesh and doing spherical harmonic expansions.
