Dear Pushpendra Yadav
unfortunately it is not possible to restart GW calculations.
What you can do, it is to generate different input for different k-points and bands range
for example
yambo_gw1.in with
Code: Select all
%QPkrange # [GW] QP generalized Kpoint/Band indices
1 | 3| 8| 9|
%
run them in different folders with
yambo -F yambo_gw1.in - J GW1
and the another input yambo_gw2.in with
Code: Select all
%QPkrange # [GW] QP generalized Kpoint/Band indices
4 | 7| 8| 9|
%
yambo -F yambo_gw2.in - J GW2
and then join the result with the command ypp -qpdb m
and setting
Code: Select all
QPDBs # [R] Quasiparticle Databases
QPDB_merge # [R] Mergering
%Actions_and_names # [QPDB] Format is "what"|"OP"|"prefactor"|"DB"|. OP can be +/-/x(only for Z)
"E" |"+" |"1" | "GW1/ndb.QP" |
"E" |"+" |"1" | "GW2/ndb.QP" |
%
run ypp, and it will joint the two results in a single database
best
