Thank You very much, Professor for such priceless materials. Thanks to You, I was able to use FEMM correctly. Thanks from Wrocław University of Environmental and Life Sciences.
Thank you very much for these videos! I did the FEMM solenoid tutorial before watching. Watching you drive the tool made some things about the interface much clearer.
4:03 I have just seen that there is a mistake in the inductance equation. It should be: L=N*B*A/I, the final equation is correct though. Sorry about that!
Hi thank you for the content. I have a question. When I try to set default boundaries as you do in the video. I have such an error: "No current magnetics input in ficus stack traceback". I do everything as you do. What should be the reason for that? Thanks in advance.
Professor Antônio, thanks for the explanation, it was really enlightfull. Do you know how can I calculate the inductance on a frequency based problem? Because the formulas doesnt work the same within a DC solution
You have to do a time harmonic analysis. You can see an example of this type of analysis here: th-cam.com/video/t8P40DWLCXU/w-d-xo.htmlç Thanks for your nice comment and question.
Sorry for my late answer. I was travelling last week. This is a common problem in physics. It is called the finite solenoid. The induction B on the axis is calculated as the addition of the contributions to B of each turn. You can find the solution of this problem in the following book for example: Electromagnetic Fields and Waves. P. Lorrain and D. R. Corson. Third Ed. 1979. Chapter 7. Section 7.7.
Hello Marcos, Thank you so much for nice lecture Requesting you, can you please do simulation of 3 phase inductor in femm with foil (higher current ratting) winding and CRGO core(like M3 or M4) and how can we find out total losses and linearity curve for same.
This is the best explanation on how to use this software. It is very precise, very well explained in every respect. Wonderful job!
Thanks!
I installled the FEMM in 2018. But... Today in 2023 I could work with it on my tasks. Thank you so much for your videos!
Thank you very much for your nice comment!

You are very welcome. Thanks for dropping this nice comment.
Your tutorial really helped me to get started with femm and it made me more curious to learn more about magnetostatic simulations. Thanks a lot.
Thanks for your nice comment.
thank you very much for making this materials available professor.
You are very welcome. Thanks for your comment!

Thank you very much for your nice comment and for watching the videos!
Thank you very much! Even if the usability is not the best, FEMM in combination with octave is really powerful.
I agree. Thanks for your comment
Nice free access tool. Good presentation. Thanks a lot Marcos
You are very welcome, Paco. Thanks for watching!

Outstanding Job.

Hi, thanks for your question. All files are available at github.com/marcosalonsoelectronics/FEMM-1
Please, download and compare with yours.

@@MarcosAlonsoElectronics Thank you very much, professor! I will look into it, and maybe write there as well
very usefull🎉🎉🎉❤
Thank you! 🙏
How did you get the formula for L & B @ 4:00

Hi, Mohammad, thanks for watching and for your suggestion.
Thank you!!!
