Hi,

If I want to implement a time-varying Newton constant G in CAMB, where would be the best place to implement that ?

grho and dgrho variables are used in many places and I was wondering if there is a single place I could set the "modified" G and it is used everywhere ?

Thanks,

Alireza

No sorry, you'd have to edit the code in quite a few places to do that.
