I have no experience with ornamental grasses but I have been doing lots of investigating during the 'off season' looking for grasses which can succeed in shade.
All of these look wonderful and have been described as (quite?) shade tolerant:
Hakonechloa macra 'Fubuki'
Hakonechloa macra 'All Gold'
Carex 'Ice Dance'
Chasmanthium 'River Mist'
But now I need your experience. Have you had success with any of these grasses in a 'shady' location?
