CM NGF file example.
CM First generate NGF file(S) using NGF_RADIAL4.NEC or NGF_RADIAL8.NEC
CM Then run this file to use one of both *.NGF files and complete the structure 
CM
CM Note that you manually will have to set the number of segments when using
CE more complex NGF files. See 4nec2.hlp (F1) or read 4nec2.rtf
