Dear Rong The behaviour you found can vary dramatically depending on the system (a run dominated by diagon or ordern will not notice the variation in mesh cutoff, while a run dominated by dhscf will)

Dear All, It seems the mesh-cutoff does not significantly influence the calculation time. For FCC Pt, the used mesh-cutoff and the total time are listed as follows: ============================ Mesh-cutoff (required, used) time 60 76 214 100 136 239 200 213 240 ============================ Is this normal? If yes, I wonder why not set default mesh-cutoff to a larger value, say 200? Thanks, Rong
