[QE-users] Epsilon.x Error

[saramoh at tezu.ernet.in]

Hello,
I am doing optical propeties calculation for hetero structures using
epsilon.x
However, using epsilon.x for optical properties, when i set wmin= 0.0d0,
in espr.dat file for 0.0000 energy i dnt get any number.I got stars
******* instead of number in real part corresponding to 0.000. For
imaginary part,there is no such case.
Sir, may be this question is a trivial one but please suggest what should
i do?

1.could we set wmin= 0.01d0 , or anything except than 0.0d0.?
2. Is it physically acceptable?


Waiting for your kind response. Thanking you.
