[petsc-users] getting a field's Vec from a DMPlex

[Ataollah Mesgarnejad]

Dear all,

I was wondering if someone can tell me how you get a field's Vec (subVec of
the global Vec) from a distributed DMPlex. It seems that DMCreateFieldIS
works for sequential DMPlex but gives incorrect values for a distributed
DMPlex.

Many thanks,
Ata
