why i have different answers
i have used three programs in order to get gain and impedance (MANAMA,PCAAD,4NEC2) i have give the same parameters but each program give me different answers why i cant understand as i know these programs uses the same method (MoM) and i want to ask how does MoM operates (how does it work ..i need information about MoM
Please show your model, show results, show difference. What is your reference?
Different simulation packages based on the same method might require specific model preparation actually. Something must be wrong with the models. Have you tested convergence of results - decreasing mesh-size of the structure and controlling results change?
