This is the second release of the NEC pre-processor WireGrid for Windows (WinWire). WireGrid has been developed by EM Software & Systems in collaboration with the University of Stellenbosch (Stellenbosch, South Africa). We have used it for a number of practical modelling problems and found it extremely useful. The most useful feature is the automatic wiregrid generation feature for equivalent conducting surface modelling. We have many ideas for improving the code --- but would appreciate contributions/suggestions from any person using WireGrid. We suspect that there could be a number of BUGS. We would therefore appreciate it if you can inform us of the BUGS you have encountered while using WireGrid.
