      I downloaded the qucsdoc zipped file, and I am just looking for documentation on the ports.  I am not understanding the meaning of X,Y,Z directions but if I could see the design in 3D it would make sense.  Perhaps that could be something cool.

      When I run a 3dB Wilkinson power divider, the design produces an EM solution, but I can’t see S22, S33, only S11, S21, and S31.  why are the other solutions omitted?  I would like to plot them all.  S32 for example to see the isolation between ports. Any idea how to enable all the ports.  Below is the project.

      2.4GHz Wilkinson Power Divider

      RESPONSE… Note I can’t plot S32, S22, S33.  It does not show in the S parameter list.
