Meshing for a conductor that is tinner than its skin depth

jerometeoh917

Good afternoon,

Recently I came accross of a conductor that is tinner than the calculated skin depth.

I believe I just dont need the layer mesh option?

Any strategies for this?

 

Also, what is the benefit of meshing the skin layer or without meshing the skin layer.
Is it to account to sharp changes of currect density?

 

Thanks,

Jerome.

@Abdessamed  I think you missed the question

If the skin depth is more than the size of the conductor, then you won't have a skin effect in the conductor and will probably have an homogenous current density.

In general it is important to have at least 2 elements in the skin depth to ensure the correct computation.

--> If the skin depth is bigger than the conductor, you can even define the conductor as a coil to save computation time. But any mesh should work fine.

--> If it is a bit smaller you need to mesh it carefully. Making sure you have those two elements in the skin depth

--> If it is so small than meshing it would be difficult, then here you should use impedance surface method which will take this very small skin depth into account virtually.
