Hi all,
I am trying to optimise pb3 with LSORBIT=true and PAW potentials. The calculation stops after finishing the first ionic step.
what might be the problem.
I will send the files if required otherwise

thanx in advance,
rajesh

yes, please. if you set NSW, IBRION, and all the other ionic relaxation parameters correctly, the calculation should continue, unless all forces and stress tensors are 0 (or smaller than the required convergence limit)
