Dear Peter Blaha and WIEN users<div>I was trying to solve the problem of electronic structure of 'Graphene' using WIEN 2K. For this purpose I provide a=b=1.42A, c=0, angles alpha=90, beta=90, gamma=120 and space group 191 (P6mmm), so as to obtain StructGen for graphine, but the software does not accept c=0 and it automatically makes c=1.42A, which is not true for graphene. Though it works well for graphite when value of c is given. Can any body help me how to use WIEN 2K for 2-dimensional and 1-dimensional problems.</div>
