Hi Everybody,
for those interested, we published on GitHub a new version of the EM Workbench, and here you are two new tutorial videos explaining how to use the latest enhancements, centered around:
1) define a conductive plane ht ps://youtu.be/5pSzPizw4e8.
2) parametrize the position of the nodes ht ps://youtu.be/BeBNtfH25rM
Enjoy, and any feedback is welcome as usual! Enrico |

Dear Enrico,
thanks a lot for this fantastic tool, it gives a turbo boost to the discretization process ^^
By the way, assuming a 3D model of a via has been built using FreeCAD or imported as a STEP file, is it possible to discretize it accurately (including wall thickness)? And if yes will fastHenry be able to process the resulting structure (calculate resistance and inductance)?
I wanted to ask you this question before I start experimenting to avoid "chasing the unicorn" :)
Also, as a separate subject, any news on the feature allowing the use of linear magnetic materials?
Many thanks,
Marco |

Yes and no. The FastHenry input format is based on parallelepipeds, which are not conforming to arbitrary 3D models as tethraedrons, for example, would be (for flat surfaces or approximations of flat surfaces). However, you can use the 3D model imported via STEP as a 'trace' for creating a FreeCAD model using the E.M. workbench tools that could be exported in FastHenry format (BTW I assume we are talking about FastHenry here).

Not at present. This is still in the roadmap, but not having found any sponsorship for the time being, this is de-prioritized versus other activities. If you would be interested in further discussing this topic, kindly contact me via email (I'm not sure if I touched the point with you earlier, but your question makes me think so; I'm sorry I cannot at the moment connect the dots).
Best, Enrico

Dear Enrico,
I've tried to send you an email but I received the following error
Microsoft VBScript runtime error '800a000d' Type mismatch: 'rs' /forum/pop_mail.asp, line 228
Perhaps if you send me an email I could reply.
Thanks for clarifying the capabilities of the fastHenry format. It looks like for complex cases like the one I described, at least for resistance calculations, it's better to use other methods.
With regard to my question on magnetic materials, I believe you have discussed this topic with another user, this is my first post. Having open source solutions capable of tackling self/mutual inductance with magnetic materials is possible but its not straightforward. This is the reason for my interest in the subject.
Regards,
Marco

This is strange. However you can find the email address in the same 'contact us' page. It is: support < a.t. > fastfieldsolvers.com (of course you need to replace the < a.t. > with the proper symbol, due to anti-spam)

Agreed. Available for discussing.
