Hi Oded,
Two things:
1. The documentation originally stated that "Files generated using Cubit
11.x, 12.x and 13.x are valid", but I see that its now been updated to
include 14.x and 15.x. I personally don't know whether this works with
newer versions of Cubit, but hopefully it has indeed been tested.
2. You've not provided all of the data necessary to recreate your geometry:
CUBIT> create sphere radius 1
> Successfully created sphere volume 1
> Journaled Command: create sphere radius 1
> CUBIT> sculpt parallel volume all processors 8 fileroot "sculpt_parallel"

Can you please provide all whatever files are necessary to recreate the
geometry? Either that or provide the actual Cubit file itself. Hopefully I
can open it in my older version of Cubit.
Regards,
J-P
