[Wien] convergence problem

Dear Sir,

I am trying to run SCF with (min -j "runsp_lapw -ec 0.0001 -cc 0.001 -fc 5
-p -i 100" but I am not able to achieve the convergence.
The structure attached in below link is 25%Zr substituted PrMnO3 at Mn site.

The structure file is here: PrMnZrO3.struct
<https://sites.google.com/site/dftfatima5/letter/mailing-list-queries/PrMnZrO3.struct>
rmt is reduced by 3% and then further reduced 0.2 for Mn and O.

I tried with 5% and 7% rmt also but SCF did not converge.

The current SCF is still going on with four SCF steps with 160, 43, 28, and
59 SCF cycles (with PORT).

I read the optimization notes from UG (5.3.2) and what I understand is I
should run the SCF with NEW1 instead of PORT.

In another job the SCF is going on with the same structure attached above.

The parameters I am using are RKmax 6.5/6.0( for PORT/NEW1), k-points: 200
(6x6x4)

The information from the NEW1 approach is below:

1 :ENE

:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.52387601
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.46436612
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.39739099
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.32534588
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.26005026
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.22290833
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.19985624
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.23662538
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.42773647
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.63463959
:ENE  : ********** TOTAL ENERGY IN Ry =       -89856.84342128

 The original PrMnO3 was also converged after a couple of SCF cycles.

I do not what more information I should provide. So please let me know if
anything else is required to understand the conversance problem.

I would be grateful if I could converse scf with your kind suggestions.


Waiting to see a prompt reply.


Warm regards
