Features and Functionalities¶

How do I produce 1D slices through the 2D plots in the GUI?¶

Visualize horizontal and vertical slices:

Menu View => Show Horizontal and Vertical Slices (or click on appropriate button)

Export horizontal or vertical slices:

Right-click on 2D graph, Export horizontal/vertical slice as data (.dat) or as image (.png).

Is there a way to produce a 1D (or 2D) plot of some result, for example the probability density with the conduction band edge superimposed? In other words, can the GUI show multiple plots at once?¶

Yes, this is possible. Multiple output files can be shown at once, see Overlay feature documentation.

What is the difference between “List view” and “Tree view”?¶

In/For the Output tab of nextnanomat, you can switch between these options using: Tools ==> Options ==> View ==> Output folder browser

List view is the default and shows a list of the top level output folders. Tree view additionally offers the possibility of showing the subfolders within the output folder panel.

If you want to sort your output folders by date, List view is better suited.

How to prevent fonts from changing back to Calibli in the input tab?¶

Problem
As our text editor is based on Rich Text Box WinForms its behavior may be sensitive to the choice of your Keybord Language. Certain input languages for your keyboard, e.g., English (Germany), may cause the editor to write in Calibri font instead of your selected editor font, which you specified in Tools/Options/Editor.

Note

Calibri is a default font of Windows.

Your desired font is restored upon saving the input file which updates the syntax highlighting.

Solutions
If you have other language settings already installed, you can consider switching between them to see if one of them is supported. If so, then you can use this setting to write codes in the input file with nextnanomat. You can do it using a shortcut Start + Space.

If you are lacking supported language settings for your keyboard, then go to Settings / Time & Language / Language and Add a language.

Some known supported language settings for keyboards are:

English (United States)

English (United Kingdom)

German (Germany)

Polish

Known not supported language settings for keyboards are:

English (Germany)

Japanese

How can I add additional debug information to the LOG file?¶

Within the nextnanomat options Options: Expert settings some flags can be found which add additional information to the log file. Please check the following flags and re-run the simulation so the log file will include this information:

‘Include simulation time in log file’

‘Include memory usage in log file (units: MB)’

‘Include additional debug information in log file’

Can I pass additional command line arguments to the executables of simulation tools?¶

Yes, this is possible. Go to Tools ==> Options ==> Expert settings ==> Command line

For nextnano³, one could use for instance: -database "D:\My folder\nextnano3\Syntax\my_database_nn3.in

-threads 4
