Having used various forms of Spice over the years, I tend to think that
HSpice is the only tool possibly capable of performing accurate simulations
on a coil. Unlike other varieties of Spice, you can input actual geometries
into HSpice, and providing you have appropriate models, you may be able to
get some reasonable results. I also tend to think that this task would be
formidable to say the least.
A simulator that performs analysis on fields may be better suited to the
task (like Quad Design's TLC). However, to do an accurate simulation with
TLC, you need to do a layout of the geometry using CAD tools, and
backannotate the geometrical design to the simulator.
