>Dear Mostafa

 

Thank you for your useful suggestions. All the examples and tests work well for me now after I have checked the corresponding pseudo files.

 

Beside, two questions about the pseudo files I do not understand, take Ni.pz-nd-rrkjus.UPF as example, which is attached below.

 

I thick the columns followed by the “nl  pn  l   occ  Rcut  Rcut US   E pseu” are used for generation the pseudo, what is the meaning of pn? The pseudo was generated with a Scalar-Relativistic Calculation, is it spin-polarized?

 

And what about the meaning of the four fields “SLA  PZ NOGX NOGC” indicated in exchange-correlation line (colored in red). I have checked the instructions of UPF, but not find the answers.

 

Regards

Fei

Dear Fei

As the message indicates there is a problem in reading the norm conserving pseudopotential file. I think this may also be the reason why example01 did not work because it uses NC PP for Si. 

Try the attached version of the H and O PP used in the H2O test. The attached worked for me. Or may be download a Si NCPP from Q.E website and try again example 1 (of course after modifying the name of the PP in the input file). Or even try example with Ultrasoft PP to see if it works at all with your compiled version of Q.E.


Also diff the attached with the ones you have to see what is the cause of the problem.
