Hi Nuo –
Periodic boundary conditions are available in the finite element features of APBS – but require some guidance to use. We haven’t implemented periodic boundary conditions in the finite difference multigrid part of the code because it would require some substantial changes. However, we are considering non-multigrid (and therefore less scalable) approaches for periodic boundary conditions. Would this be of interest to you? It would be great to collaborate on this.

Hi APBS developers,
From googling, I know that there is no periodic boundary condition in APBS yet (right?). But this seems to be a useful feature for a number of problems, so I have 2 questions here:
1. Will the next release contain periodic boundary condition?
2. May I know why the periodic boundary condition hasn't been implemented? a lack of public interest? or hard to program?
I ask this because I'm thinking of adding a periodic boundary condition feature myself.
Thanks a lot!
