[Pw_forum] Problem with tetrahedra method for calculations DOS

[Yedu Kondalu]

*Dear Karim Elgammal,*


*  Thank you for your reply. I am not switching from fixed to tetrahedra
method, both the methods were used separately.  I want to use tetrahedra
method to calculate the DOS.  When use the occupations=tetrahedra,  I am
getting the above specified error. *

*Regards*
