Dear Minoru, Thank you very much for this clarification! I finally understand it now! I have now tested my example and saw that there is no difference between a 10 angstrom vacuum region and a 20 vacuum region on either side of my slab. This is good news for me for my future calculations!

Dear Lucian, By using esm_bc=bc1, you can obtain the desired results. In this case, dipole correction is not necessary. If you are calculating a system with no net dipole, the electrostatic potential on both sides will be flat and at the same level. On the other hand, if the system has a net d

Hello all, Is it possible to use the " assume_isolated='esm' ", with the " esm_bc='bc2' " flag for a slab geometry and perform the dipole correction? I have tried with 'esm_field=0' but it doesn't seem to enforce the 0 field in vacuum. Rather it just performs a regular scf calculation with no
