coaxial exciting coils

Hello

I hope I correctly post this discussion.
the problem is: I have a coil on a metal cylinder with two bottom open. this coil are excited by a circuit that is sending data in 100 khz rate.
also I have another coil inside the metal cylinder that is connected to a receiver circuit.
What kind of software I should use for modeling and analysis?
how to I should find the best values for L of coils?
can you suggest me some related document?

note: I'm electrical engineer and familiar with electromagnetic theories.

thanks for your help of any kind

So you know that the metal cylinder is shorting the field of the coil and the coupling between both coils will be very low?

It's an axisymmetrical AC-magnetic problem. It can be solved e.g. with Quickfield or FastHenry.

thanks for your help FvM. it was very beneficial.
I know that the field will attenuate sharply. anyway I should design, analysis and make this structure.
Also the inside coil will move linearly on cylinder axis.
Can these software model moving part like what I have?

"Moving" isn't but changing the coupling continuously, I think. You can calculate it for a number of positions and interpolate between the solutions.
