Dear all,
I have performed the GW calculations and then run ypp -s b to interpolate the GW band structures.
However, I met the error like:' [06.02] Interpolation@work: Circuit
===================================
[INTERPOLATION] Number of shells: 10
[WARNING]Allocation attempt of delta of zero size.
[WARNING]Allocation attempt of h_mat of zero size.
[WARNING]Allocation attempt of star_2 of zero size.
[WARNING]Allocation attempt of ipiv of zero size.
[ERROR] STOP signal received while in :[06.02] Interpolation@work: Circuit

My ypp.in shows below: 'electrons # [R] Electrons (and holes)

Anyone knows the possible reasons?

Re: Ypp band interpolation error
Dear yanjiaxu,
is too low. Which version of the code are you using ?
Can you attach the report of the setup and any the file produced during the interpolation run ?
Best,
D.
Code: Select all
[INTERPOLATION] Number of shells: 10
Can you attach the report of the setup and any the file produced during the interpolation run ?
Best,
D.

Re: Ypp band interpolation error
Dear Davide,
My yambo version is 4.5.1.
I think I got the reason. I turn to used more k-points during DFT calculations instead of Gamma point and the error disappears.
Best regards,
Jiaxu Yan
