debuglevel

Calling sequence

quantum{ debuglevel = ... }

Properties

• usage: $\mathrm{optional}$

• type: integer

• values: $z\ge 1$

• default: $z=1$

Functionality

The higher this integer number, the more information on the numerical solver is printed to the screen output. Increasing the respective debug level to 2 or more significantly increases the volume of the diagnostic output displayed in nextnanomat (or a shell window). As result of the additional I/O load, particularly 1D simulations will slow down correspondingly (especially for current{} and poisson{ }).

allow_overlapping_regions

Calling sequence

quantum{ allow_overlapping_regions = ... }

Properties

• usage: $\mathrm{optional}$

• type: choice

• values: yes or no

• default: no

Functionality

Overlapping quantum regions computing the same band(s) are not allowed. Note that, in case such overlap is allowed, the quantum densities of the respective regions are added in the overlap region and a too high density will be computed. Thus, please only allow such overlap when the quantum densities are known to be extremely small in the overlap region.
