Hi, I carried out GW+BSE calculation, but I can not find dielectric function in the output. My calculation procedure is:
first step: GW
the INCAR is

ISMEAR = 0
SIGMA = 0.05
ALGO = EVGW0
LOPTICS = .TRUE.
LPEAD = .TRUE.
NELMGW = 4
MAXMEM = 7848
LWAVE = .TRUE.

tail of the stdout is

performed 3557000 updates of chi_q(r,r)
total number of BLAS operations 409494.38 Gflops
resolving degeneracies of screened two electron integrals


calculate QP shifts <psi_nk| G(iteration)W_0 |psi_nk>: iteration 4
writing wavefunctions
entering main loop
Computing time is 1 Hours : 20 Min : 4 Sec.


Second step: BSE
the INCAR is

ISMEAR = 0
SIGMA = 0.05
ALGO = BSE
NBANDSO = 4 ; NBANDSV = 8
OMEGAMAX = 100
MAXMEM = 7848

tail of the stdout is

BSE (scaLAPACK) attempting allocation of 0.000 Gbyte rank= 32
allocating two-electron 4 orbital integral table 4 8 4 1
BSE setting up matrix

BSE redistributing all elements
BSE diagonalizing double prec. matrix (PDSYEVX_ZHEEVX)
BSE writing out 0 eigenvectors
BSE calculating oscillator strength
Computing time is 0 Hours : 0 Min : 46 Sec.

All the input files and the OUTCARs are attached.

Hi,

If there is no error or warning, the BSE dielectric function should be written into the vasprun.xml file.
Also, you have not attached the files.

Dear Alexey,
Thank you! It is in vasprun.xml.
