When setting LWANNIER90 = True along with KSPACING = 0.1 in a slab calculation, I obtain the following error:

This error repeats several times in the error file. I will also copy the input files below. The calculation is for a charged defect in MoS2, but the same error appears for the uncharged case. This is being run on vasp 6.2.0 with an interface to Wannier90 3.1.0

Since this error report specifically said to file a bug report it only seemed appropriate to file a bug report. I am going to simplify the INCAR substantially to see what I can remove as a possible source of error. Ill try to keep this thread updated

Thanks for the report, we will look into the problem.

Can you please still post your calculation according to the forum guidelines (we need POSCAR, INCAR, POTCAR, KPOINTS, OUTCAR and stdout).

Yes, I will attach the zip file here. There is no KPOINTS file because I was using the KSPACING tag, but I attached the IBZKPT instead.

Generally one cannot use LWANNIER90=.TRUE. together with NCORE.NE.1!!!

Unfortunately there is no proper error handling in the latest release version. We already fixed this issue and in the next update there will be a proper termination of the code with an error message stating that LWANNIER90=.TRUE. must be used together with NCORE=1.
