In 2008 sp1 a NlogN solver is added which should reduce simulation time significantly with large problems (> thousands unknowns).

Trying it with a simulation having 5000 unknowns (single layer, no holes but thick conductor with side currents) I note that the loading matrix phase (N2) is largely dominant in respect the simulation phase with all the methods, N3to NlogN).

So I should expect that for larger problems, using either the iterative solver or the NlogN solver the simulation time should increase as N2because loading time reamains dominant.

Is It correct?
