In ACDC module, what the max. operational frequency limit. It is possible that , ACDC module work upto100MHz(opeartional frequency). I try to work, but didnt get good result. Anyone have same experience like that.
wait for ur positive reply.

Hello Fovad,
a FEM-Simulation of harmonic electric fields is only accurate, if the skin depth is resolved with at least three elements, says a rule of thumb. So check your materials and mesh size. For example, with copper and 100 MHz, the skin depth equals 0.00655 mm, which is considerably small. If you want to resolve that with three mesh elements, their maximum size should be 0.00655 mm / 3 = 0.00218 mm.
You will also have to find out, if the quasi-static approximation is valid in your case or if the dimensions of your model require for a RF simulation.
