[Pw_forum] Possible bug in PHonon 5.4.0

[Timrov Iurii]

Dear Prasenjit Gnosh,


The subroutine dv_of_drho.f90 was moved from espresso/PHonon/PH to espresso/LR_Modules, because there have been some restructuring in the Quantum ESPRESSO 5.4.0. You may try to comment out the lines 65 and 66 in dv_of_drho.f90 and see if this solves the problem (I think it should). Did you do any modifications in the code or use the original version 5.4.0? The check lines 65 and 66 were introduced in order to avoid the wrong usage of this subroutine in other parts of Quantum ESPRESSO when trying to use the non-linear core correction in some specific cases.


Could you report please the input files of your calculations (PWscf and PHonon), version of the compiler and libraries, and the information about the machine on which you run the code. This will be very helpful for us to examine closer such a wrong behaviour of the code. Thank you for reporting!


Best regards,

Iurii

Subject: [Pw_forum] Possible bug in PHonon 5.4.0

Dear developers,

I was trying to do phonon calculations with version 5.4.0

The calculation crashed with the following message:

     from dv_of_drho : error #         1
     drhoc is not present in the input of the routine


When I tried to look for the dv_of_rho subroutine, I do not find the file in the distribution. However, in version 5.3.0, there is a file "dv_of_drho.f90" in the PH directory.

With regards,

Prasenjit
