Indeed it seems to work with the 5.4.4 (on platine calculator). I will try and use it on my cluster.
Thanks.

What's the result with the official version of Abinit ? (v5.4.4)

sorry for the lack of information. Here is the full output, the log, and the input. WARNINGS signal a high value in the matrix, but not that high, and this high value is due to the pseudo.
Thanks

Hello all,Etot and etotdc are equal when SCF cycle is strongly converged.
I am using abinit with paw and I am getting strange total energies for a simple 8 Germanium atoms on a diamond lattice computation : /Etotal/ and /Etotal (DC)/ are completely different.
But there, in your case, there must be an error; it can be a new buggy developpement (for which people did not test the etot-etotdc comparison)...
You gave too few informations to help us to make an opinion.
Why would that be? Could it be the pseudo?no, it can't !

Here is what I get ( The results are well converged, <e-8 ).
