Hi SL,

There doesn't seem to be a China Steel 35CS210 in the student version database. There is one in the Junk_Test_01 project though, I wonder is there a way to add that material to the database?

Other than that I just finished plodding through this first exercise and I'll tell you, I'm going to have to go through it several times before I really start to grasp things. It's a good exercise to start getting familiar with the software though. Well done.

This next is another topic, so feel free to edit it out.
Linux users can use the Ansys software by creating a Windows 10 virtual machine for it. I highly recommend that you NOT enable any network adapters in the VM! A Windows 10 iso file can be downloaded from Microsoft and installed in the virtual machine for free. That might be a good thing for Windows users too if your PC can run it. With 4 processors and 8 gigs of ram for the VM it runs fine. By aware you will need no less than a 60GB virtual disk to install Windows 10 and Ansys and have room for projects. I used 60GB and I think I should have used 80.

Looking forward to more tutorials SL. Just give us old guys a little time to absorb them Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

Hi Cadman,

China Steel 35CS210 should be in the Material data base - a few ways to get there - e.g.
"Core | Properties | Material: Edit (takes a while to load), then "Search by Name" for 'china steel'
(scroll around a bit) and hopefully it's there somewhere... see attached cartoon.

- Check that the "Show Project definitions" and "Select all libraries" are checked (in the upper Materials
window to the right of "Libraries.").

Also, yes, material data can be added to the student version but it's a little involved. We'll
go through that, since it seems some of the good materials have been encrypted in the student
version while some others are are not in the database at all.

Thanks for the Linux tip. I don't use it so the insight is appreciated.

Take your time - I'm an (very) old guy as well so I can appreciate what it takes, but I'm optomistic
this AEDT might be of some assistance in working with parts of the devices.

Note, there are limits and restrictions to the student version, however I'm working on them;
including having the founder of Ansys (name blanked) grant a small group of EEG developers
some assistance down the road. A good chance since he's actually one of us! We shall see...

Just thought I'd throw this in for "shits and grins"

Don't fret - a startup can be open source, also! Many are, Linux...

Thanks SL.

"Select all libraries" did the trick. Then used the search for China Steel 35CS210 and it popped right up.

Will your tutorials take us to the point where we have the means to simulate an operating device? Something like you did with your LinGen, with output waveforms and all? If this Student version of Ansys can do that, well, that would be great.

I really appreciate what you are doing and have done for us. Thanks a million.

Hi Cadman,

Unfortunately AEDT Student does not allow for "Transient Analysis" which is required to fully simulate the
mechanism required to actually transfer the magnetic field. 

Faraday's Law says that a moving magnetic field around a conductor (coil) or a conductor that moves through 
a magnetic field generates EMF. Transient (time variations) are needed to do this, so, for now at least, the
short answer is no. Magnetostatics and Eddy Current simulations get us close, but no complete cigar.

Many other circuit parameters can be simulated (using Maxwell Circuit) in AEDT Student but the real cruncher
(Transient) is blocked.

I'm starting to think this AEDT Student excercise might be boon-doggle with respect to what we need to
accomplish unless we find a way of getting access to the full blown AEDT.

I could simply describe the V2 design and hope it is replicated by others but without understanding the
somewhat complex theory it would likely end up like the LinGen - no interest and ultimately scrubbed
from the forums - anyway, so much for Open Source development! A waste of time on my part and nothing
more than a Joke according to the forum community of builders at large.

Hi SL,

Maybe, maybe not. Speaking for myself I can already see it’s usefulness, as-is. To be able to model cores and coils and assign materials and currents as needed will be very useful. Being able to see the resultant magnetic field and its properties, also extremely useful.

That said, I just finished a first run building a simple model from your post https://www.mooker.com/thread-47-post-591.html#pid591. It took awhile but I got there. I hope you don’t mind, there were a few things that confused me because the instructions at that point weren't clear to me so after I figured it out I edited your instructions a little. I’m attaching the edited instruction file from Junk_Test_01.zip if you are interested. I think it would help a beginner.

Man, don’t get discouraged. Keep at it. Please.

Best Regards

Dear SL

I'm also appreciateing for what your are sharing here,
But would you pls tell us which package of Ansys is full and will fit our needs? There are bunch of diffrent analytical Ansys tool ( produt, motor, maxwell, electronics,...) which one we are looking for as ultimate tools in our future steps?

Hi Ar_AH,

The "full version" I use at the Lab says its "Ansys Electronics Desktop" and has the same icon
(see the AEDT Icon.PNG posted above) as the "Ansys Electronics Desktop Student."

The Computer IT and the local Ansys Rep sort that stuff out - all I do is let them know what
I need to accomplish and they take care of it - sorry I can't be more specific.

Note however, that the files between the Full version and the Student version are not
compatable - AFAIK, I can't seem to move files back and forth between the two.
Another bummer.

In the Windows program bar (lower left windows cartoon) the Lab Workstation says
"Ansys EM Suite (year and rev)" while the Laptop with the student version says
"Ansys EM Student (year and rev)."

The web seems to have some Ansys Electronics Suite stuff that might be the same
[large GB file]; but that could be a big crap shoot - I don't know!

SL

Cadman, thanks for the edits, appreciated...

AR-AH - let me inquire, have you installed and tried the AEDT Student version?

Hi SL

Actually not yet, whereas i have access to have any of them, i was looking for one that fullfill our needs ,specially  performing transint analysis too.
,And as you instructed, i will go with complete electonices package.

EEG EM  =>  EXCESS ENERGY GENERATOR using ELECTROMAGNETICS
ANSYS Electronic Desk Top (AEDT) Student version download link:
https://www.ansys.com/academic/students/...op-student
  (Built-in license valid until 07/31/24) [zip file 8.3GB] Has some limitations.
-----------------------------------------------------------------------------------------

Attached is some information regarding the original LinGen V1. This design stems
from the Holcomb patent given in the text.

There is/was a thread outlining the design and development at OUR.com that
included the technical details along with the "does it actually work" approach
to evaluating the methods and techniques provided by Holcomb.

This might be a good place to start when looking at the technology involved.
Patent numbers are given and can be found on Google Patents. It ties
together the process of patent/idea discovery and the ultimate verifications.

Having gained some insight and encouragement from the LinGen1 V1 study
and analysis another (much better ?) design, V2, followed. 

Disposition of the V2 is still under further consideration and evaluation. TBD.

AR_AH,

Please be advised that the only "instruction" that I make is to download and use the
"AEDT Student" package!

I recomment nothing more... and will not address further discussion except, possibly, the use
of AEDT Student.

SL

PS - personally I don't like the way this is heading, it's a discussion about developing an Excess Energy Generator
and various ways this might be accomplished; including some available tools that might be of assistance - nothing 
more.
