Dear VASP user,
I am doing site projected and lm-decomposed DOS for a CdS cluster of 5 atoms(1 Cd and 4 S) using us PP. So i have to mension RWIGS in the INCAR file(because mensioning LORBIT=11 is allowed only for PAW ). But i am little confused in assigning the values of this tag (by reading manual and some previous mail regarding this point). I have assigned these values from POTCAR and the result written at the end of OUTCAR file is the following:
+++++++++++++++++++++++++++++++++++++++++++++++++++++=
volume of typ 1: 0.4 %

volume of typ 2: 0.6 %



total charge

# of ion s p d tot
----------------------------------------
1 0.664 0.657 9.795 11.116
2 1.453 2.359 0.010 3.822
3 1.453 2.359 0.010 3.822
4 1.453 2.359 0.010 3.822
5 1.453 2.359 0.010 3.822
------------------------------------------------
tot 6.48 10.09 9.84 26.41

But according to the manual, the sum of the volume should be close to 100%.

What should i do in assighing RWIGS ?
Another question is if i increase the cluster size, should i also change the value of RWIGS?

Any suggession in this point will be highly appreciated.

Best,
Soumendu

I'd say since you calculate your cluster in a large cell with surrounding vacuum you will never get a 100% filling of your unit cell.
