Dear sir Thanks for your reply. The problem that i found in selecting mesh cut of is that the total energy is constant for cetain ranges of mesh cut energy is constant like in 70 Ryd to 110 Ryd it is -296.671577. Then from 120 Ryd to 140 Ryd it is -296.683935 so on.

I would like to know what value of mesh cut off should be selected. Thanks Mamta
