Farfield3dIntegrate function not working in optimization sweep

      Hi all, I am trying to use the farfield3dintegrate function as part of a figure of merit for the FDTD optimasation feature, but am getting a message saying this is not a valid function despite it working fine in the script environment. The code i am using is below.

       

      E = farfield.E2;

      E=pinch(E);

      ux = farfield.ux;

      ux=pinch(ux);

      uy = farfield.uy;

      uy=pinch(uy);

      NA=0.3;

      acceptangle = asin(NA) *360/(2*pi);

       

      out =1;# farfield3dintegrate(E, ux, uy, acceptangle);

      out1 = farfield3dintegrate(E, ux, uy, 90);

       

      powernorm= abs(power);

       

      fom = powernorm * (out/out1);

       

      Farfield is defined as a result in the optimization fom environment. Can anyone suggest why this function may not be working?

      Did you use those script inside Optimization ? it only holds certain script to work there. The best way to do this is in the "model".  Then you choose its output as the FOM during the optimization. Please try.
