I'm trying to simulate electrical contact through oxided metal, and i use the contact impedance boundary condition as the properties of oxided layer. and i use both direct and iterative solver. however, the results came back showing that the admittance is negative at some frequency range. it doesn't make sense.
Anyone help me.
