Dear all,

I'm using the following input files

Al.abinit.files:

Al.abinit.in
Al.abinit.out
Al.abinit_xi
Al.abinit_xo
Al.abinit_x
Al.abinit

which Al.abinit is the PAW potential; The input is

Al.abinit.in:

Code: Select all

# ---------------------

# 3-Parameters governing the convergence:
# ---------------------------------------

# 4-Options for the choice of calculation:

ngkpt 2 2 2
#ngkpt 1 1 1

# 7-Symmetries of the lattice:
# ----------------------------
chkprim 0
chksymbreak 0
diemac 12.0

The problem is that it does not start the scf iterations and pops the message

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

If I tried with ngkpt 1 1 1, it runs fine. Trials with kmesh larger than 1x1x1 gives this error.

The information of compiler:

The only modification for installation on MacOSX is described here in Homebrew formula abinit

I don't think this modification is relevant to this issue. Any help is appreicated, thanks!

Hello Loukai,

Welcome to the Abinit Forums!

While I do not know the answer to your question I do believe that your question is in the wrong sub-form. The correct place for this question is in the "Platform specific questions" sub-form where your post would receive more attention.

Thanks Nick. You are right, I didn't realize the section for platform specifics.
