Thank you for the reply. My code is MPI parallelised, how can I use the condense() function with ghost values mentioned in the AffineConstraints class?

You can't. You need to apply constraints during the assembly of the linear system if you work with parallel linear systems. I think you probably want to look at step-86 as well.
