file extension NWP - NEC-Win Plus proprietary file format
File extension NWP description:
For more information see related links.
NEC-Win Plus use proprietary file formats. The .NWP file format is based on a spreadsheet input system that allows the program to have some special functions. Bridging the gap requires reversion to a .NEC file.
NEC-Win Plus permits saving any model in .NEC format. Some things saved in the .NWP files, such as model-by-equation spreadsheet entries, cannot appear in the .NEC file. The .NEC file is always the file of a specific model with a certain wire table having numeric entries, along with program control cards that reflect these values...
Standard EZNEC 3.0 does not have a provision to import files in .NEC format, nor a provision to save files in this format. However, the Pro version of the program has both potentials. Whether or not one needs the NEC-4 core, if one reaches the point of investing in multiple programs, upgrading to the Pro version of EZNEC may make sense.Associated applications to file extension NWP:

NEC-Win Plus:
This powerful NEC-2 antenna modeling program contains most of the wire structure and control input features that the majority of antenna designers need for developing better antennas. Virtually all features are accessible from the main screen, including frequency sweeping, ground selection and specification, radiation pattern plot requests, and tabular data selection. The user can request multiple plot types, and the program will generate them for each frequency, even in a large sweep. Besides standard polar plots, with detailed analytical data, the user may select both impedance and SWR graphs.
The wire structure provides several convenient features, including standard AWG wire size selection (as well a entering a custom diameter) and an extended list of preset wire conductivity values (in addition to user specified values). Conductivity may be set for each individual wire, permitting precise modeling of antennas using multiple materials. R-X and R-L-C loads are available, as well as networks and transmission lines. Unique to NEC-Win Plus is a complete spreadsheet model-by-equation facility for the development of new antennas or the creation of master models that alter all dimensions with the entry of a new design frequency or a new element diameter.
The NEC-2 core used by NEC-Win Plus is the fastest available, reducing the run time on large models by over 50% (depending upon available RAM). NEC-Win Plus handles up to 9,999 segments (subject to operating system limitations). As well, NEC-Win Plus can directly access NEC-Win Synth and receive synthesized wire-grid structures directly into its wire table.
