Dear Robin Cornelius, I have downloaded your program, put it in a directory with fkn, triangle, femmview, femmplot then (from a command line in a DOS wimdow) I typed femme-lua.exe test.lua The FEMM program start with nothing into it. What I missed? Many thanks in advance. Roberto Brambilla CESI Via Rubattino 54 20134 Milano tel +39.2.2125.5875 fax +39.2.2125.610 rlbrambilla@xxxxxxx
