Transformer bug ?

[Christian]

Dear all,

I noticed something quite weird in the calculation of transformer, using Vizimag.
Considering 2 straight solenoids, one with current and the other without.
Simulation, then running the Transformer Analysis, based on the designed models.
Defining the primary voltage, frequency, and number of turns and resistance for primary and secondary.
Plus the load resistance, for secondary. Then calculate.
Currents, winding power, efficiency are calculated, plus coupling coefficient and mutual inductance.

Here comes my problem.
Even if I change Magnet settings from "In Free air" to "as Specification", coupling and mutual inductance would not change.
If I change the voltage on primary, these two parameters would not change too.
And the values of coupling coefficient seems strange: 100% really often.

Do you have any information ?
If needed, I could upload some simulation files.

Regards

There was a bug here, but it has been corrected. Just download the trial again and reinstall.
