You are not doing "virtual crystal approximation" (where one changes the occupation by a few tenth of an electron), but you are changing the atom. If you change Z by two, do also the initialization with an atom of Z=Z(W)+1,2,3,... Am 12.12.2013 00:56, schrieb Hena Das: Dear All, Using Virtual

If you change Z of (the atom you initially named) W by one, that is from 74 to 75, then you have Re but NOT W ! Wien does not care how you name an atom but only the number of Z matters and Z=75 is definitely not longer tungsten. Ciao Gerhard DEEP THOUGHT in D. Adams; Hitchhikers Guide to the

Dear All, Using Virtual Crystal Approximation I am trying to do total energy calculation by varying occupancy of 5d level of W^+6 ion. I did a normal initialization first, and afterwards changed Z in case.struct and case.in2 (not in case.inst) and then submitted a scf calculation. Change in oc
