Dear Niels, I am probably not the most suited to answer and, probably, the best mailing list to address this problem is the qe-developers one (q-e-develop...@qe-forge.org). Moreover, it is not fully clear to me what you are planning to do (Ewald sum is only part of the electrostatic energy of

The title says it all--Has anyone ever tried to replace the 3D Ewald sum in quantum espresso with a quasi-2D slab Ewald sum (yes, I know, that would not be general, and requires on using certain type of crystal unit cells). If it has bot been done, am I daft to think it should not be a total mi
