Current Calculation in HFSS

Hi Everyone!

I am working on a project and need to obtain the current passing through a wire.
But the wire is not a common one. It consists of two layers. The cross section is circle and both layers (i.e. Inner one and outer one) are good metals. I want to calculate the current passing through each layer. I use calculator but even when I set the domain to specific layer I get wrong current. Please help me!

Thanks!
