Hi Corrado

Repeat the debug run without the SYMMETRY ORTHORHOMBIC constraints in the &CELL sections. It might interfere with the numerical stress tensor calculation.

Hi everyone,
I attach input/output and initial guess geometry of a DEBUG calculation on a MOF.
I run this debug since the cell was getting heavily distorted during an AIMD run.
I kindly ask what should I modify in the input to calculate the correct stress tensor.
Thank you very much for your kind attention and help
Corrado
