Interactive Graphics Utility for Army NEC (Numerical Electromagnetics Code) Automation (IGUANA). Installation Guide.

摘要

The Interactive Graphics Utility for Army NEC Automation (IGUANA) is a system designed to reduce the time required for antenna model evaluation by providing partial automation to both the data entry and the data display processes. Previous to this system, the use of existing Numerical Electromagnetics Code (NEC) for antenna evaluation required a lengthy, tedious, and error-prone process involving manual measurement of three dimensional coordinates of each significant point of the desired input structure from scale drawings (generally only top and side views are available), and manual entry via keyboard. IGUANA automates much of the above described process using a personal computer, a digitizer for input of the model wire end points from the top and side scale drawings, a graphics monitor for the display (including rotation and zooming capabilities) of the input data and resulting structures, a mouse for the editing of the structures, a plotter for the production of a hardcopy of the structure in various stages of completion, a printer for generating a hardcopy of data files to be sent eventually to the selected NEC host computer, and a modem to transfer data to and from the NEC host computer.
