I’m trying to do the finite electric field calculation (berryopt=14) for antiferroelectric materials (40 atoms, nkpt=10).

It takes very long time, so I would like to use kgb parallelisation (LOBPCG or Chebfi).

I set up the flags (paral_kgb=1, npband=2, npkpt=10, npfft=1) and ran the calculation, but the calculation didn’t work.

I would like to know whether the band parallelization is available for finite electric field calculation.

I found a similar question in forum (URL : [SOLVED] band parallelisation in finite electric field? - ABINIT Discussion Forums), but it was too old.

Could you teach me the recent information?

Best regards
