[Pw_forum] PS generation

[Dariusz Chrobak]

Dear PWscf users,

I would like to create pseudopotential for Co using uspp-7.3.5 package.
My file for all-electron calculation is as bellow:

    1    0    0    0    3             ifae,ifpsp,ifprt,ifplw,ilogd (5i5)
   2.8     -2.       2.       80    rlogd,emin,emax,nnt (3f10.5,i5)
   1.0d-10   1.0d-09    0.3            thresh,tol.damp (2e10.1,f10.5)
Cobalt                                title (a20)
  27.   0.0       5.                  z,xion,exfact (f5.0,2f10.5)
 200.0        7.0       60.0          rmax,aasf,bbsf (3f10.5)
 8     2                            ncspvs,irel (2i5)
 100   2.    -660.8                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 200   2.    -145.2                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 210   6.     -19.9                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 300   2.      -3.7                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 310   6.      -1.4                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 320   7.      -0.6                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 400   2.      -0.4                 nnlz,wwnl,ee (i4,f7.3,f14.6)
 410   0.      -0.0                 nnlz,wwnl,ee (i4,f7.3,f14.6)

Maybe someone know how  to  avoid  the following problem:

========================================================================
pseudopotential program version  7.3.5   date:  3 - 17 - 2005
========================================================================

 ifae =   1    ifpsp =   0    ifprt =   0    ifplw =   0    ilogd =   3
 rlogd=   2.80000     emin=  -2.00000     emax=   2.00000     nnt=   80
 thresh, tol =   1.000E-10   1.000E-09    damp = 0.300    maxit = 250

          *************************************************************
          Cobalt               PBE - GGA           exchange-correlation
          *************************************************************

 z = 27.00    xion = 0.00    exfact =   5.00000    irel=   2
 ncspvs =    8
 rmax = 200.00000    aasf =   7.00000    bbsf =  60.00000

 value of mesh generated in rinit is   937
 irel = 2 so all electron calculations use koelling-harmon equations
 ***error in koesol
 classical turning point too close to mesh
