[petsc-users] PCSetCoordinates does not set coordinates of sub PC (fieldsplit) objects

Dear community,

I am working on a block preconditioner, where one of the blocks uses
HYPRE's AMS. As it requires the coordinates of the dofs, I have done so to
the PC object. I expected the coordinates to be inherited down to the
subblocks, is this not the case? (it seems so as I couldn't find a
specialized FIELDSPLIT SetCoordinates function).

If this feature is missing, please give me some hints on where to add the
missing function, I would gladly do it. If not, please let me know why it
was dismissed, in order to do things the hard way [as in hard-coded ;)].

Kind regards,
