I want to add one more query and want to explore part of question 2 For example, 1. In a case of the optical properties for a system where we have a,b and c different. In such case we define xx, yy and zz in case.inop and get three components in the case.epcilon file. Does it simply mean that such materials are anisotropic along three directions? 2. Is the average value at zero energy of a real part of dielectric constant is static dielectric constant? if not then how we can get from the output file of the case?
