I've a problem starting the LUA script file. the following message pops up:

error: No current magnetics input in focus

stack traceback:

1:function 'mi_analyze' [C]

2:main of file '...y Documents\DomusPMFSM_modellingNopera\flux.lua' at line 7

Attached are my FEM file and Lua script file.

Please help.

regards,

aaron
