Free 3-D EM Software for Modeling Transformers and Mapping Poynting Vectors

AI Thread Summary
Free 3-D EM software options for modeling transformers and mapping Poynting vectors were discussed, with a focus on student editions available in other threads. Users expressed disappointment in the cost and GUI of commercial software like Ansoft, while acknowledging the limitations of free versions. A specific transformer design software was mentioned as potentially useful, along with links to additional resources. Overall, the conversation highlights the search for accessible tools in electromagnetic modeling. The quest for effective free software continues among users.

Does anybody know of free 3-D EM software so that I can model a transformer?

In particular, I'm interested in mapping Poynting vectors.

Thanks.

Many thanks.

I looked at the "Ansoft" product & found out how much it cost ... I would have expected a better GUI to be honest with you.

Having said that, "beggers can't be choosers" so I shouldn't moan about it.

There doesn't seem to be bags of help in the SV. I suppose that's one of the things that makes it the SV, not the full-blown version.

I'm also finding it difficult to use.
 
Hey, I just came across this transformer design software. Looks interesting -- I may try it out.

Excellent! ... Thanks very much, I'll check it out.
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
