    Closed: Re: value error self inductance simulation in CST

    Let me ask you a question.
    Do you think if you put one port on this conductor and the other side on the regular conductor, the result will be the same?

    Closed: Re: value error self inductance simulation in CST

    Ah, because the current flows through the boundary condition, is it calculated by the length that it contains?
    The boundary conditions are as follows:
