[Pw_forum] Is it possible for all-electron calculation on anions with ld1.x?

Dear all,

I am generating pseudopotential these days and happening to meet lots of unexpected problems. One of which is, when I run the all-electronic calculation on anions, the error of "errors in KS equations" appears. But when I run the program on cations, it works well. I just want to do some tests on those electronic configurations after pseudo generation. Could anyone help me, thanks.

Here are the input file:
 &input
        iswitch=1,
        atom='C',
        config="[He] 2s2 2p3 3d0"
        dft='LDA'
 /

Output file:
     Message from routine scf:
     errors in KS equations
     --------------------------- All-electron run ----------------------------                                                                         

     atomic number is  6.00
     dft =LDA   lsd =0 sic =0 latt =0  beta=0.20 tr2=1.0E-14
     mesh =1675 r(mesh) =  99.50825 xmin = -7.00 dx = 0.00800

As you can see, the energy of 2P is 0.

Best wishes,
