Seems that you did not ask ABINIT to compute all perturbations
(and to decide by itself which ones were not needed owing to symmetry).
At least you should mention

rfdir 1 1 1

But rfatpol might have to be changed. Difficult to say more without input file...

Dear All,

in a calculation of elastic properties I got the following warnings :

WARNING : still subject to testing - especially symmetries.

WARNING : Localization tensor in reciprocal space incomplete,
transformation to cartesian coordinates may be wrong.

chkph3 : WARNING -
The dynamical matrix was incomplete : phonon frequencies may be wrong ...

Does anyone know what is going wrong ?

Regards,

Xenophon
