Dear Tran
I am performing YS-PBE0 on a scf (with -so) calculation with pbe-gga with
Wien2k_18.1.
I have few queries.
A.
1. My original scf(-so) has done with 7 7 5 shifted mesh. To reduce the
computational cost I am using 3 3 2 mesh for YS-PBE0 (see appendix below
how I did it).
Can we do this and if so then should we call it redklist?
2.
Again with a limited HPC facilities, how safer would be for the doss, band,
optic calculations if we go with the 3 3 2 mesh?
Also I want to use the same scf calculations for thermoelectric
calculations without additional scf.
3. Could you please correct me if I am doing any mistake in the below steps?
I am curious to know in particular: in normal dft+so calculations we do a
additional step as "lapwso" in between lapw1 and lapw2 -so.
Is it okay here if we avoid both the steps i.e. lapw1 -so and lapwso for
YS-PBE0+SO?
Steps:
x_lapw lapw2 -qtl -hf -so -p
x_lapw tetra -hf -so
run_bandplothf_lapw -p -qtl -redklist
x_lapw spaghetti -hf -p -so
x_lapw optic -hf -p -so
x_lapw joint -hf -p -so
x_lapw kram -p -so
Appendix:
$run_kgenhf_lapw
If you type 0 you can give 3 integers for nx,ny,nz
0
How many in x?

How many in y?

How many in z?

Do you want to shift? (0=no, 1=shift)
