Hello everyone!
I present to you my program for the calculation of transformers and inductors.
One of them ( ExcellentIT(6100) ) Dimonis you presented in your theme SMPS transformer design tool.
The program ExcellentIT(7100) was corrected English translation and added standard AWG wire and the added choice of the desired diameter wire.
selector is not signed due to lack of space, but it is a tool tip.
In other programs, this selector signed 'Use the desired diameter of the wire'
I speak English poorly. I use Google translator.
I would be difficult to answer your questions, but I will try.
I'm not working, I'm retired. So I will be grateful for your financial support for my work on the development of these programs .

When the switching transistor is turn on in a fly-back converter, the primary winding of the transformer is energized, and no energy is transferred to the secondary windings. When the transistor is turned off the field collapses and the energy is transferred to the secondary windings. This differs from a forward converter topology, where energy is transferred to the secondary windings when the switching transistor is turned on. You can tell the difference between the two topologies, by looking at the orientation of the dots on the secondary compared to the primary. For the fly-back converter, the dot's are reversed, and for the forward converter the dots are aligned.
The calculator below calculates the number of turns, the inductance, and the wire gauge for the various windings of a discontinuous mode fly-back converter.
