Does polarization =2 means”Fundamental TE mode”?

      Hi,

      There are sentences :

      # set polarization
      if GC_settings['polarization']=='TE':
        polarization = '2'
      elif GC_settings['polarization']=='TM':
        polarization ='3'
      lumapi.evalScript(_globals.FDTD,"select('FDTD::ports::port 1');
      set('mode selection',%s);" % polarization)
      lumapi.evalScript(_globals.FDTD,"select('FDTD::ports::port 2');
      set('mode selection',%s);" % polarization)
      


      Polarization =1, it means port will select dundamental mode.

      Polarization =2, it means port will select dundamental TE mode.

      Polarization =3, it means port will select dundamental TM mode.


      Is it right?

      Yes, you are right.
      You can also test a FDTD file with port. For example
      setnamed("FDTD::ports::port 1","mode selection",2);
      will select the Fundamental TE mode.
