? including what effects... (read physically coupled/dependent elements)
the more the slower and error prone --
• unless using tabulated functions and/or
• unless using (also time resolution) limited range and/or
• unless using simplified response models

/!\ The fine tuning / debugging such model for practical use ("fast" simulation in LTSPice) may take longer (months) than figuring out the model's logical construction

PS! → you very likely CAN NOT use this model for predictive purposes --
-- the reliability for simulation correlating with real world is below 33%
(that unless you specially tune a particular simulation for the particular actual device parametrics)
. . . but again the more exact the more slow


. . . thus
Why are you convinced you need such model ?
For what you need the model ?

Hello,

To sim or not really depends on what the TS wants to get out of the simulation.
It's really a 3 phase AC generator with some output rectification.
