You do wrong what can go wrong.

EELS of a single atom ??? Think about: what states does an atom have ? Do you have a "DOS" ? How would a "DOS" look like ? Which transitions are allowed in EELS and how would a hypothetical EELS spectrum look like.

Your modifications of case.in1 have at least 2 errors:

Dear Community,

Version 23.2

My calculations run fine when I do init_lapw -prec 1 -hdlo and make no changes in the case.in1 file.

I would like to add multiple LOs at much higher energies (HELOs) for a better description of unoccupied states, hence as per the guidebook pg 151 last paragraph, I add them in the case.in1 as shown at the end of the email.

After this, I do run_lapw -ec 0.0001 -cc 0.001 -p

But the code crashes and shows the following error.

STOP  LAPW0 END

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

MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD

with errorcode 0.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.

You may or may not see output from other processes, depending on

exactly when Open MPI kills them.

My question is

 1. Is there something else I need to adjust after I add them in the
    case.in1 file? (I have included the original and modified case.in1)
    ? Please note, the calculations runs fine in parallel mode if I
    don’t do any changes in case.in1 file.

 2. I am unable to figure out how to proceed and have been stuck at the
same place for a long time. Requesting your attention please.
My original case.in1 file is

WFFIL  EF=-.43330239753334999845 Old -.10000 -0.5999535963  (WFFIL, WFPRI, ENFIL, SUPWF)

And the modified one is as below.

Requesting your help.
