Dear Paolo, Thanks for your reply. I can contribute two files of force constants: one for a 5x5x1 mesh, with which matdyn.x works, and one for a Gamma only mesh for the same system, for which matdyn.x produces the error.
I can also contribute the dynamical matrix files generated by ph.x, from which the force constants are generated using q2r.x Running q2r.x and matdyn.x is inmediat[Be, you know better than me. Is it enough? Can I sent you an attachment with a tar file? On the other hand, the calculation of the dynamical matrix for the gamma point takes several days in a single CPU. I hope it is not needed.
