Dear Prof. Blaha and Dr. Kroeker

Thank you for your prompt responses and attached file. As suggested Dr. 
Kroeker, I increased the numbers in arbmsh.f. The stars **** disappeared in 
outputkgen files. I also used the wien2k files attached by prof. Blaha and it 
works properly. However, I still have problems with xcrysden. When I increased 
both MAX_NKPT=999999 and MAX_IRNKP= 20000 in original wn_readbakgen.f file and 
I get ERROR: while executing wn_readbands program: Error Message: STOP NKP TOO 
SMALL. It seems this error I get when the Wien2k No. Of INEQIVALEN K-points is 
above 9999 (in my case, for 200 000 k-points, I get 13776  No. Of INEQUIVALENT 
K-POINTS and the xcrysden ERROR, but for 140 000 kpoints with 9324 INEQUIVALENT 
k-points there everything is working properly). For the file attached by prof. 
Blaha, I get errors during compilation (without any changes inside):

gfortran -O2 -c wn_readbakgen.f
wn_readbakgen.f:110.33:

            read(line,'(43x,i7,err=111)') nkpt                          
                                 1

                                                                        1
Error: Label 112 referenced at (1) is never defined

Thanks in advance,

Re: [Wien] maximum number of inequivalent k-points in case.outputkgen

I attach a few subroutines for SRC_kgen, which have been changed for larger 
formats. They should now not produce "***" up to 1000000 k-points.


The problem is, that for 1 000 000 k-points, you also have to change 
wn_readbakgen.f in xcrysden. (Or you do not change the "6000 format line" in 
reduz.f ( and stay at max 999999 k-points.)


When it works, please let me know.

    Dear win2k-user,

    I am running wien version 14.2 and have similar problem to that observed in 
    thread 
    
http://wien.zeus.theochem.tuwien.ac.narkive.com/pXOQN5tX/maximum-number-of-k-points
     - the answer does not work for me. I also try to do calculation a Fermi 
    surface with a very dense k-mesh (above 100000, Spacegroup: 129_P4/nmm), 
e.g.: 
    x kgen 120000 or using xcrysden

    In my case.outputkgen file, the maximum number of inequivalent k-points can 
    only be lower than 9999. When the number of k points is larger, it gives 
***** 
    in the rows, as shown below:

    case.outputkgen
    9997(  0.234479  0.456618  0.000000)9998 (  0.234479  0.456618  0.012504)
     9999(  0.234479  0.456618  0.025008)**** (  0.234479  0.456618  0.037512)

     ****(  0.234479  0.456618  0.125040)**** (  0.234479  0.456618  0.137544)

    in the reduz.f file i have 100 format(i6,4x,3i4,i8,2f10.5), so everything 
seems 
    to be ok. I checked this out using gfortran and ifort compilation on two 
    different machine type and still the issue persists. Can you help me?
