Dear All,<br>
<br>
Recently I started to dig a code of Quantum Espresso to compare it
with the developed in our group and found that many PAW UPF files
have divergence in AE and PS radial wave functions. I found that it
appears mostly in 4th P-orbital. Here I post two plots with these AE
radial functions for V and Cu<img

<br>
Looking at the other files I found such problem in each of them. It
seems that all PAW UPF files have such divergence. <br>
<br>
Interesting point, that Quantum Espresso gives no bad values in
density (variable "rho_lm") and potential (hartree, xc, total), but
variable "pfunc" has such divergense. <br>
<br>
Due to these divergences our developing code gives bad values in Dij
matrix, because it is calculated in a little bit different way.<br>
<br>
I would be very appreciated if you could help me to explain such
strange behavior.<br>
<br>
With best regards,<br>
