The charge convergence of the scf takes very long time and i want to use the old .clm for new one in finding RKmax or k-mesh process. When i save_lapw the old program and start new one by the previous .clm, is it necessery to run all of initial steps (i.e nn, sgroup, symmetry, lstart,...) for changing k-point (or RKmax) or changing only the value of k-point (or RKmax) is sufficient.<span lang="en">I 'm not sure of the accuracy of the latter results.</span> Is there other solution for this problem.<br><br>Best Regards.<br></body></html>
