Non-Uniform K-grid

Hello,

I've recently noticed some discussions around the forum regarding a yambo flag called "NoDiagSC". I'm not sure if I understood correctly its meaning, but does it allows one to perform GW and/or BSE calculation on non-uniform k-grids? Thank you in advance.

ps. I think this post is on the wrong part of the forum, so sorry about that.

Regards,

Dear Bruno,
NoDiagSC is used to make the setup of the k point grid, especially useful for non diagonal cells solving (hopefully) the problem of non recognizing the k grid as uniform from the standard algorithm. GW/BSE calculations on non uniform grid is not allowed.

Best,
Daniele
