[Wien] EOF on case.clmcor on second iteration of HF calculation

[Falke, Johannes]

I am trying to run a computation with a hybrid functional calculation. The Wien2K version is 14.2. (quite old, I know, but currently the machine is running some outdated libraries which are not supported in 19.1). Sadly, I cannot search the mailing list archives since there is some https protocol error, so I apologize if this question has been asked before.

After converging run_lapw with the standard PBE functional, k-mesh 8x8x8, save_lapw -f, I run init_hf_lapw, input again k-mesh 8x8x8. If I then run "run_lapw -hf", run_lapw spits out errors on the second iteration.

forrtl: severe (24): end-of-file during read, unit 19, file /path/to/case.clmcor

$ cat *.error
error in hf
[...]
error in hf
**  Error in Parallel HF
**  testerror: Error in Parallel HF

(same thing in a non-parallel computation) Looking at case.clmcor, it is empty. At which point is it supposed to be generated? I cannot find much information on this file in the documentation. It is already empty after the non-hybrid normal PBE run.

Best regards,
