​Both calculations converged to -cc 0.0001 before 40 cycles, but the case with previous .clm converged rapidly. Actually i test these two calculation to be sure that the results are same or not. As i know in volume optimization also the old .clm use for next volume by clmextrapol_lapw technique. I use this technique and the result was different with the case without using previous .clm. Also i use GGA-PBE as xc-potential.Can the value of the k-points be matter?
