Computational domain discretization
Controlling the discretization
As an example, in order to change the discretization spacings along $x$, $y$, and $z$ to 2 nm (from their default values of 1 nm), the following could be added to the parameters file:
domain disc 2.0e-9
or explicitly set the discretization along each direction:
domain disc 2.0e-9 x domain disc 2.0e-9 y domain disc 2.0e-9 z
The latter case also demonstrates how one may modify the discretization along directions non-uniformly.
