[Pw_forum] US not implemented error of D3Q

[Min Hong]

Dear QE users,


I am doing d3q calculations. I am not using ultrasoft pseudopotentials. But, there is always an error:


from d3_readin : error #  1

US not implemented


Could you help to fix this error?


I have tried with pseudopotentials of pbe and pz to run phonon calculation, which are not ultrasoft. But I still get this error.


In my calculation, when I use nonconversing pseudopotentials, there is error of "S matrix not positive definite". So, maybe nonconversing pseudopotentials cannot be used in this calculation.


Thank you very much.


Kind regards,


Min Hong
