#Input file for the anaddb code. Analysis of a restricted SiO2 DDB
#Will use only the Gamma point information : compute
#Compute LO-TO splitting for different directions,
#as well as the dielectric tensor at zero frequency

#Flags
 dieflag   1     ! Frequency-dependent Dielectric tensor flag

#Effective charges
 chneut  2       ! Charge neutrality requirement for effective charges.
