No.
This depends on the details of your reaction.
The correct procedure is to use converged k-meshes, i.e. test each
single calc. for k-convergence such that E-tot is changing less than your
required
accuracy.
If your reaction is: metal + molecule -- insulator
you need probably MANY
In standard WIEN2k this is NOT possible.
a) edit run_lapw (or whatever script you use) and comment the call to the
program lcore.
b) After init_lapw (before run_lapw) you've get a case.vsp file from lstart.
run x lcore , which will produce a core density and case.scfc file
coming from
Dear Y. Ding,
For the material Fe2O3 having the formal high-spin Fe3+ and a closed
up-spin shell, I think LDA (when giving an insulating solution) or LDA+U
partial d-DOS can well show the t2g-eg (if being eigenorbitals) crystal field
splitting.
Just a note: have you worked with a hexagonal
