Dear users
We are trying to use Wien2k. After down loading expanding all the files we
could compile all the program successfully except warnig in param.inc in
cif2struct. param.inc is the following file :
parameter (mxsym=192,mxcen=8)
common/comsgt/ iga(454),ipga(454),idla(454),itxta(454), &
grupaa(454)
common/cellc/ Cell(6)
common/symm/ ns,ncs,NcSym,nvt,mr6(36,mxsym),rm6(36,mxsym), &
s6(6,mxsym),vt6(6,mxcen),centr,latt,ngrupa, &
CrSystem,Monoclinic,BratSym(mxsym), &
ndim,ndimi,ndimq,ShiftSg(6), &
.;.;.;.;.;.;.;.;.; WARNING IN THIS LINE
lattice,grupa,symmc(6,mxsym),smbx,smbc
common/units/ dta,out,FormA1,FormA80,Cislo
character*30 itxta,grupa
character*15 cislo,symmc
character*8 grupaa,smbc
character*7 FormA1
character*5 FormA80
character*4 lattice
character*1 smbx(3)
integer dta,out,CrSystem
logical NcSym
2. After loading localhost.localdomain we tried to generate main
masterfile using graphical user interface W2WEB .
> For this purpose we declared a file name BN
Required number of atoms is set eqal to 2
With the result two input files are generated
(i) BN.struct containts copy of the case.struct for
atom 1. for atom 2 the local rorational matrix are taken as 0.0000.
(ii) BN.struct i contains initial part as copy of
BN.struct. It was appended with 'symmetry operation but followed by
no matrix.
Selecting any operation it never
reads number of symmetry operations.
When we chang number of symmetry
operations from 0 to any number, matrics elements for that number
of operations are printed but
showing all elements equal to zero.
Example :
Title
P 2
MODE OF CALC=RELA
0.000000 0.000000 0.000000 90.000000 90.000000 90.000000
ATOM= -1: X= 0.0000000 Y= 0.0000000 Z= 0.0000000
MULT= 1 ISPLIT= 8
NPT= 781 R0=.000500000 RMT= 2.00000 Z: 0.0
LOCAL ROT MATRIX:
1.0000000 0.0000000 0.0000000
0.0000000 1.0000000 0.0000000
0.0000000 0.0000000 1.0000000
ATOM= 2: X= 0.0000000 Y= 0.0000000 Z= 0.0000000
MULT= 1 ISPLIT= 8
NPT= 781 R0=.000500000 RMT= 2.00000 Z: 0.0
LOCAL ROT MATRIX:
0.0000000 0.0000000 0.0000000
0.0000000 0.0000000 0.0000000
0.0000000 0.0000000 0.0000000
0
After changing symmetry operation by 24 we get the form of BN.struct as
