I do not think it does not matter
because if i have 10 secondry turns and 20 primary turns
1 i wind first secondry turns
2 i wind first primary turns
in these two cases legnth of the wires changes (I THINK I'M NOT SURE)

My friend, you can find some advise and technical reasons for placing the primary in between alternating layers of a flyback SMPS transformer.

Hi Dimonis
Thank you for a great effort
Some small observations:
1. No help available.
2. Not intuitive placement. The output data is in the middle of two input data. Not a problem, just an observation
3. Addition of material type different from the list you have provided, does not seem to work. The core dimensions are accepted, as well as the core data like Ae and Ve, but the core material name is not being accepted in the list.
4. If the core chosen produces power less than the required output, then why is the option displayed as output? Or maybe a color change could be used to signify to the user that he is going the wrong way?
5. Is there any possibility of more topologies also? like Forward, Sepic, Cuk and so on
6. What about designing inductors also?
7. What about updates o the software?
8. What about systems where there are more than one switch in parallel?
All in all, an excellent initial effort. Needs polishing, thats all
Once again, Thank you very much.

Hi guys, Dimonis
Its only now I see my post has put in smileys that I hadnt intended. I wanted smileys, not rolleyes
The entire post changed meaning with those wrong smileys.
Sorry for any misunderstanding being caused.

Hello Michelle and MicrosiM, I am interested to follow the project and cooperate.
Can an ETD59 deliver 2 KW ?
Kind regards

Isn't it a little bit offtopic ? I mean this thread is devoted to a design tool , and not to SMPS in all !

It's up to you! It depends how convenient for you.
As for me , I always wind the primary first.
