    Ok, now I created an index inside the subfunction in this way: i=0; if t ~= 0 load('i'); end i=i+1; save('i'); Now there is another problem: I'm wondering if this procedure could affects the simulation time returning me wrong values

    50 Hz vs 60 Hz and frequency changer

    It depends on what type of "appliance" you are using. If it is just an electric motor or pump it will simply run slower with more torque, but if there is an ac/ac drive you have to control if your converter is suitable for both frequency. Anyway, if you look at the data sheets you'll find the...
