Nice website for modelling structures in Ansoft HFSS， CST， Feko， IE3D etc..

Hi ,

I found a nice link for modelling simple structures such as dipole using various EM softwares.

Evaluation of Electromagnetic Modeling Tools

This web site is a bit dated. For instance, Flomerics MicroStripes is actually now a component of CST Microwave Studio. There are other technical issues on this web site that make it appear to be at least 3-4 years old. When you are comparing the technical capabilities of various commercial EM software tools, this is a very long time for relevant, current information.

This also has some inaccurate information in it. On the HFSS dipole, it is simulated over the range 50 MHz - 400 MHz, but the text says:

"For this simulation, the solution frequency is 300 MHz (λ = 1 m). The radiation boundary is defined on a cylinder whose radius is 500 mm and height is 2000 mm. "

So whilst the 500 mm is fine for use at 300 MHz (and even 150 MHz, as λ/4 should be just about ok), it will not be suitable for use at 50 MHz, where the boundary is only λ/12.

If the results are going to be shown to 50 MHz (λ=6m), then the boundary should be at least 1.5 m (λ/4) away, so 500 mm is not sufficient.

I learned this flaw from an Ansys engineer recently while attending a course on HFSS.
