Starting with Installer

1. Install the package

Unzip downloaded package to your preferred location, run the unpacked MSI file, and follow instructions of the installer nextnano Setup.

2. Run the nextnanomat GUI

You can achieve it in two ways. Either select the checkbox Launch the nextnano software at the end of the installation process to open nextnanomat immediately after successfully finishing the installation. Or run nextnanomat using the automatically generated shortcut or by double-clicking the nextnanomat executable file in the installation directory.

3. Optional, install .NET Desktop Runtime

If prompted by nextnanomat, follow the link in the pop-up window. The nextnanomat GUI version 5 or higher requires .NET Desktop Runtime libraries to be installed on your computer to run. If they are not present, then the following error message will be shown at application start.

Open nextnanomat again after the installation of the runtime.

Upon the first run, nextnanomat is opening an input file with a selected simple simulation.

  • Open an Input tab of nextnanomat, if not already, to preview the input file defining the simulation.

  • Click the icon runsimicon to run the simulation.

  • The nextnanomat will automatically choose the tool matching the input file to run simulation; In this case it will be either nextnano++ or nextnano.NEGF.

  • Confirm that you want to run the simulation.

  • After it finished, go to the Output tab, where you can preview the simulation results.
