Dear all

i would like to ask whether the use of the extrapolar method is known to have an important effect on the convergence properties of other paremeters.
A large increase in ecuteps (the size of the dielectric matrix) seems to accompany the extrapolar method (as compared to the full-contiuum calculation).
I mean, about twice as much (this implying a memory increase).

Is there any experience with that?

thanks in advance
