Dear Dr. Lorenzo Paulatto, thank you very much for your clarification. I understand now that nqx1 = 2, nqx2 =2, nqx3 = 1 or nqx1 = 4, nqx2 =4, nqx3 = 1 (or 6x6x1 or 12x12x1) should not cause any problem as my nk is 12x12x1. But the program stopped after the com

Dear all, I'm trying to do a hybrid calculation of a monolayer of graphene-like material for the sake of calculating band gap. The following are the details (important part of the code is geven below): &system ibrav = 4, celldm(1) = 7.5284, celldm(3) = 5.020259255 , nat = 1
