Front End & Workflow Manager

nextnanomat is a GUI for editing input files (ASCII, XML), organizing simulations and submitting jobs (directly or via a batch list), as well as visualizing, post-processing or exporting simulation results. Parallel job execution is supported on multi-core CPUs automatically.

Overview and Download

nextnanomat is customized to work with the following software:

• nextnano++
• nextnano³
• nextnano.NEGF
• nextnano.MSB
• any other scientific software that is general enough to be executed from the command line, reads in one or several ASCII files, and outputs the data in a nonexotic output format

nextnanomat can be used as a visualization software for 1D, 2D and 3D results (e.g. somewhat “similar” (but much simpler) than Origin, Gnuplot, Compaq Array Viewer, Intel Array Viewer). The focus lies on quick visualization rather than on professional editing of graphs.

Visualization features:

• 1D data: x, fi(x)
• 2D data: AVS/Express and VTK format, Aij format
• 3D data: AVS/Express and VTK format (i.e. 2D slices through 3D data)
• 1D slices through 2D data (incl. export)

• Slices (*.vtr, *.png, *.dat)
• Pictures (*.png)
• Gnuplot
  • 1D (including overlay)
  • 2D colormap,
  • pseudo-3D/surface plot (color, mesh, colored mesh)
• Vector (*.pdf, *.svg) (intermediate step over Gnuplot necessary)

Instead of creating tons of input files manually, you can specify the variable to sweep and create the input files automatically.

There are many output files after a variable sweep. To visualize the changes of one output parameter in respect to the swept variable, it could be useful to use the post-processing-feature of nextnanomat.
