Hi all, I've been running a vc_relax calculation on a 40 atom system. The calculation worked fine for some cycles. The total force had come down to 0.108 and when the no of cycles was complete, I started another calculation with the final atomic positions and lattice parametres. In this new file, the force started increasing and it increased to 0.2 and now the iterations don't converge even in 400 steps. The CELL parameters are :- [&Ions/] / &CELL cell_dynamics= 'damp-w' , cell_dofree='xy' , /
Please tell me where am I making the mistake. Thank You. Best Regards, Vishal Gupta B.Tech. 3rd year Mechanical Indian Institute of Technology Ropar Rupnagar (140001), Punjab, India.
