[Wien] TEMP option

[John Appleton]

Dear WIEN2k users,
   
  when I run a job, I sometimes get warnings about 
  electron number conservation (expecially 
  in isolated atom computations). If I switch 
  from tetra to temp in case.in2, by setting 
  TEMP to 0.005, the problem stops and 
  everything is fine. I want to know if the 
  various methods for determining Ef have 
  any effects on the details of the electronic 
  structure (e.g. total energy and DOS). 
  How does one choose a 
  good value for TEMP or TEMPS.
   Also when you read articles, they 
  say that TEMP is used to reduce the number 
  k-points needed in the first BZ. Why? 
  Finally is it allowed to used  RMTs 
  (say 1.1 and 2.4) for a particular problem 
  which differ by 60% even if there are no ghost bands 
  warnings?
   
  Thank you.
   
  J. Appleton
