[Wien] LAPW2: semicore band-ranges too large

Post by Algerien1970 on Thu 11 Jun - 21:09

Dear WIEN2k colleagues,

The ghost bands are a problem, but I have not found how to get rid of
them.
++++++++++++++++++++++++

One simple example, cubic BaRuO3

Running with

runsp -so -orb

When r*k=7 or 8 (k-points=100) it finishes without problem

but when it is increased to r*k=9

it stops in the first or second cycle at lapw2 with;

*************************

LAPW2: semicore band-ranges too large
(standard_in) 1: syntax error

-------------------------------------

I searched in the usersguide for ghost bands and found no answer for this
problem.

I would suppose that the ghost bands would not depend on the quality of the
calculation, that is, with r*k=6 or 10 or with k-points=100 or 1000.
