How do you compile wien2k ?

ifort or gfortran ? Which version ?

Could it be that your compiler was upgraded and you must recompile ?

In any case recompile, maybe with -O1 or even -O0 -C

    If not already done, also search for problems/solutions related to
    SECLR4, POTRF, or Scalapack/LAPACK in the WIEN2k mailing list.

    I have tried many times in new directories. Most probably i have to
    install scalapack/lapack and recompile wien2k again.

        As I said, it works for me. Using your first struct file and
        executing
        init_lapw -b -sp
        runsp_lapw -ec 0.0001 -cc 0.0001 -NI
        the calculation finishes properly.
        Is it really not working if you follow this same procedure in a
        new directory?
        If not, maybe there is a problem/bug with your installed
        Scalapack/LAPACK library?

        It crashes during the 1st iteration. Error occurs in
        non-parallel calculation also. I'm using the 19.2 version of
        wien2k. I ran other structures and it works fine.

           More questions:
        At which iteration is it crashing? At the first one or not?
        Is it crashing also in non-parallel calculation?
        Which WIEN2k version are you using?

        One remark:
        This second structure corresponds to FeNi, while the first one
        was for Fe2Ni.

        After initialization, I tried running the command runsp_lapw -p

        I tried with another bct structure of FeNi ( case.struct and

           Hi,

        I can not reproduce this error, at least not with default
        parameters and PBE functional.
        You need to provide more information like the functional,
        spin-polarized or non-spin-polarized,
        the command that you executed, etc.
        Besides, are you sure that your structure is correct? It
        corresponds to Fe2Ni, which seems very odd.

        Dear WIEN2k users,

        getting the error

        **  Error in Parallel LAPW1
        **  LAPW1 STOPPED at Sun Oct 4 13:53:54 IST 2020
        **  check ERROR FILES!
