<div dir="auto">It sounds like you are using "run_lapw" for your calculations. This is for non-spinpolarized cases, which is correct for many systems. If a material is magnetic, for instance Fe, then you have to use "runsp_lapw" which will produce up & dn spins.

<br>
I’m a very new Wien2k user and I am attempting to calculate DOS and ELNES for (mainly) transition metal oxides. I have installed Wien2k 21.1 on a single desktop with Intel i7. It’s slow but I hope to move to an HPC system. I am using both W2WEB and command line.<br>
<br>
Whilst I’m getting results in serial calculations (except that for some reason my calculations generate only case.vector and not case.vectordn, but I can cp to the correct name), parallel calculations are stalled after the SCF as qtl can’t read my separate case.vector_n files. The parallel scf seems to execute correctly without errors and generates separate case.vector_n files.<br>
<br>
All the case.vector_n files (n=1~4) are in the same local directory. Running x qtl -p gives the error as follows in qtl.error:<br>
<br>
‘QTL’ - can’t open unit: 10<br>
<br>
‘QTL’ - filename: ./case.vectordn<br>
<br>
‘QTL’ - status: unknown form: unformatted<br>
<br>
In this directory /case/ are 4 vector files, i.e. case.vector_1~4<br>
<br>
I have found (in the archive) and applied a patch to qtlpara_lapw, <br>

<br>
But this had no effect. It appears that qtl is attempting to read only non-existant “case.vectordn” rather than the parallel case.vector_1~4 files.<br>
<br>
I’d appreciate any advice to help me get parallel calculations working. Beginner so please be gentle….<br>
<br>
Cheers,<br>
