Hello @lgivord, and thank you for reply!
I was not able to upload hdf file because I’m a new user.
And… I just realized that I’ve been erroneously using the “global” index for the index data.
It was fixed by duplicating Points data on multiple processes and use “local” index for the Connectivity data.
I think the problem is related to the previous one, but I didn’t notice VTKHDF point ownership - Support - VTK.
Thank you
