[petsc-users] DMLocalToLocal for DMPlex

[Adrian Croucher]

hi

If I have a local vector and I want to update all its ghost values from 
its non-ghost values, should I use DMLocalToLocalBegin()/End() ?

I have tried it and it gives me an error: "This DM does not support 
local to local maps".

The DM is a DMPlex. Is the local-to-local operation not implemented for 
DMPlex?

Or should I be using something else to do this?
