I have been using transient inputs, though every time my input changes, I have resent my t back to 0 and begun recounting, so the dynamic input shouldn't be a problem Compared to simulation from ANSYS Maxwell and from test data, this appears to be calculating results which decay much slower...

If I have a circuit with R = 1Ω L = 300μH V = 20V i0 = 5A I know that I can use the equation at the bottom of page 13 to calculate the current rise given any starting current and input voltage: i(t) = (V/R)[1-e-t/τ] + i0e-t/τ This is fine, and stops increasing at 20A as expected...

In that case, how do I calculate the induced current at any time-step using a changing voltage input? The equation you specified doesn't appear to calculate the induced current, which is what I'm after?

I was under the impression (from here and a few other places) that the total current was I = V/R , but there were different amounts in the inductor and resistor as the current has to build over time in the inductor (iL), but the current in the resistor (iR) was I-iL I am expecting the current...

Ah, thanks very much, I know it was something similar, but got the wrong letter! In this case, which "I" would I use in RI? Would this also be the induced current, or just the dI/dt?

Hi, Just saw your post and had a similar problem a few months ago! If you right click your design in the project manager tree and go to "Design Settings", in there you should have a "Matrix Computation" tab, tick "Compute Inductance Matrix" and you should be able to view results! Hope this helps!

Hi, if I have a DC indoctor-resistor circuit with and inductance (L) of 700μH and a resistance (R) of 0.8Ω, I realize that I can use: IL = (Vsource/R) * (1-e-t*(R/L)) to calculate the current through the inductor if I have a constant voltage source, but would it be possible to calculate...
