gautol

Post by Vladimir_Konjkov »

Hello Casino developers.

While reading the CASINO documentation I discovered:
Gaussian basis functions can be regarded as localized if they are truncated to zero outside a certain
radius. This is done by default in casino: Gaussian functions exp(−ar²) are assumed to be zero
when exp(−ar²) < 10^-GT , where GT is the gautol input parameter (default 7).
What about slater functions in this context?

Best wishes, Vladimir.
In Soviet Russia Casino plays you.

Implementing screening appears to be on the to-do list for stowfdet.f90.

Best wishes,
