[Pw_forum] Virtual crystal approximation?

[Stefano de Gironcoli]

Dear Wangwei,
     concerning the virtual.x code mentioned by Lorenzo Paulatto, please 
take notice that very recently (after your request to the forum) an 
updated version have been uploaded in the CVS repository incorporating 
the changes introduced by Jivtesh Garg and Nicola Marzari to fix the 
code misbehavior in the (common) case where the two pseudopotentials to 
be mixed have different mesh definitions.
     Please update your virtual.f90 version and report any problem or  
misbehavior you may notice. 
     best regards,
     Stefano de Gironcoli - SISSA and DEMOCRITOS
