I have a power converter structure consisting of two busbars with four parallel paths connecting them. Current flows into one bar, through the four paths, and out the other bar. I'm interested in determining the current sharing between the parallel psths. Can FastHenry do that?
Image of the structure is at ht*p://imagebin.org/237258
And my input file is below (also at ht*p://pastebin.com/ZnDcn8YK )
Currently I have one port, at the busbars where the overall current enters and leaves. What is the trick to being able to measure the current at other locations, such as in each of the eight vertical branches?
