Nov 27, 2020 · The energy stored in the magnetic field of an inductor is. (14.5.5) U L = 1 2 L I 2. Thus, as the current approaches the maximum current ϵ / R, the stored energy in the inductor increases from zero and asymptotically approaches a maximum of L ( ϵ / R) 2 / 2. The time constant τ L tells us how rapidly the current increases to its final value.

Apr 19, 2008 · LTSpice, and it seems like the inductors never show any saturation behavior. I have even tried, for example, a stock 10 uH 10 amp inductor from their database, and applied 10 VDC. The dI/dt stays just about constant at 0.9 A/uSec up to at least 80 amps, and it only flattens out at about 2 mSec at about 438 amps, due to the 0.0226 ohms series resistance.
LTspice is designed from the ground up to produce fast circuit simulations, but there is margin in some simulations to increase the speed. Note, there may be trade-offs in accuracy using the methods...

Nov 04, 2020 · When linear models are not enough, LTspice provides the means to consider inductor saturation. We can define the function that determines the inductor flux. In order to define the inductor flux, we need to modify the netlist. This can be done by pressing the “CTRL” key and then right-clicking an inductor. This will bring up the following window:
